Dive watches at every price, compared by spec

Buy the Duro if $84.95 is the budget; nothing else on this page is under $275, and nothing above it is rated deeper until the Nodus. Casio gives 200 m, a quartz movement and an anti-reverse aluminium bezel, and publishes the case as 48.5 by 44.2 by 12.1 mm, which is 44.2 mm across and 48.5 mm lug-to-lug. The crystal is mineral and the page states no lug width and no ISO rating. Each rung above buys one thing the Duro lacks, in order: an automatic, sapphire and a ceramic insert ($275), a stated assembly location ($429), an ISO claim ($450), a Swiss movement ($805), a certificate ($1,850). The alternative for the money is a strap for something else.

At $275 this is where the ladder's first automatic, first sapphire and first ceramic bezel arrive together, in a 38 mm case after the Seiko 6200 of 1965 that the brand's own collection page calls a homage. 46 mm lug-to-lug, 13 mm thick, 20 mm lugs, Seiko NH35, 200 m, a screw-link bracelet with a fly-adjust clasp. The price is what San Martin displayed on the check date and the brand moves it often; the PT5000 and SW200 versions cost more. Two-year warranty, a Dongguan address, assembly not stated. For less there is only the Casio, quartz and mineral at $84.95. The grade 5 titanium SN0111-T at $389 and 300 m is on the under-$500 list; see the San Martin guide.

$349 buys the diver with a US retailer behind it and spare parts on a shelf. Long Island Watch's house brand built this 42 mm on the footprint of the discontinued Seiko SKX with the crown at 3: 47 mm lug-to-lug, 13 mm thick, 20 mm lugs, Seiko NH36 day-date, 200 m, double-domed sapphire with inner AR, a 120-click bezel, drilled lugs, on a bracelet. One-year warranty; assembly not stated for the automatics. For $74 less the San Martin is the smaller watch at 38 mm; for the same $349 nothing else here has a day-date. The 38 mm at $329 has the shortest lug-to-lug in the range at 44.5 mm and the Northport at $449 moves to a Miyota 9015; the Islander guide lists them.

$429 is the first rung with a stated assembly location, and the buyer who wants USA on the caseback stops here. 39 mm, 46 mm lug-to-lug, 11.96 mm before the crystal, 20 mm lugs, Epson VS22 solar, 200 m, single-domed sapphire, a lumed ceramic bezel, 20 layers of X1 lume, two straps in the box, a two-year warranty for the original owner. It is solar, which is the trade: no mechanical movement, and no service interval either. The Hong Kong-assembled DS4 at $299 is the same idea with less of it; the D5 at $729 is this case with a Miyota 9015. The Citizen $21 up gives an ISO claim and takes back the sapphire. The Vaer guide has all eleven lines.

$450 at list, and $360 on Citizen's own site on the check date, buys the only ISO compliance claim under $650 here, a five-year warranty and a six-month solar reserve. 44 mm, 49 mm lug-to-lug, the longest on the page, 12 mm thick, 20 mm lugs, E168 Eco-Drive, 200 m, unidirectional bezel. The crystal is mineral with AR, the last non-sapphire on the ladder, and the length is the other thing to weigh. For $21 less the Vaer is 3 mm shorter, sapphire and USA-assembled, without the ISO wording. The next rung, $200 up, is the Seiko King Turtle, the first ISO rating on a mechanical movement.

$650 buys Seiko's ISO 200 m rating with sapphire, a date magnifier and a ceramic insert on the Turtle case, and the case is the thing to understand. It is 45 mm across but 47.7 mm lug-to-lug by Seiko's own figure, so it sits shorter than the 40.5 mm Traska three rungs up; 13.2 mm thick, 22 mm lugs, 4R36 with hand-winding and hacking. For the same $650 the Nodus below gives 500 m and a Los Angeles assembly line, without the ISO wording or the dealer network. The SRPE93 Turtle on silicone is $525 with Hardlex and was sold out at Seiko USA on the day. Seiko's own top of this ladder, the 300 m Marinemaster SLA079 at $2,900 on an 8L35, would sit above the Monta.

The same $650 buys the deepest rating on the page from the first small-batch maker: 500 m in a 38 mm case, 42 mm across the bezel, 47 mm lug-to-lug, 13.6 mm thick, 20 mm lugs, Seiko NH35, flat sapphire, a fully lumed DLC bezel with 60-minute and 12-hour scales, BGW9 Grade A, a 20 to 16 mm bracelet with the brand's own extension clasp. Designed and assembled in Los Angeles per every product page; 24-month transferable warranty. The trade against the Seiko is availability: every colourway showed sold out in the collection data on the check date, though the Pioneer GMT version at $675 was in stock. See the Nodus guide.

$699 buys the thinnest case on the ladder, and the shortest warranty. 39 mm with a 37 mm bezel, 46 mm lug-to-lug, 10.3 mm case plus a 1.1 mm domed sapphire, 20 mm lugs, Miyota 9039, 200 m, a sapphire bezel insert with 15-minute markings, BGW9, a 20 to 16 mm bracelet with a five-position clasp. The 2026 relaunch replaced acrylic with sapphire throughout, which removes the old objection. 12 months of cover is the price of the thinness, against 24 at Nodus for $49 less and three years at Traska for $36 more. On pre-order with September shipping on the check date. The Lorier guide covers the rest of the core collection.

$735 buys a hardened case and the longest warranty on the ladder, three years and transferable. 40.5 mm, 48 mm lug-to-lug, 10.5 mm case (11.9 mm with the box sapphire), 20 mm lugs, Miyota 9039 or 9015 with date, 200 m, a 120-click coin-edge bezel with a BGW9 ceramic insert, a 20 to 16 mm bracelet with a quick-adjust clasp. Traska quotes the hardening at about 1,200 HV and does not say where assembly happens. The 48 mm lug-to-lug is 2 mm longer than the Lorier for $36 more, which is the whole comparison for a small wrist. Every colourway showed unavailable in the storefront data on the check date. The Traska guide has the Seafarer and the Commuters.

$805 buys the first Swiss movement and the first titanium case, from a maker you cannot simply order from. 41 mm, 46.5 mm lug-to-lug, 12.4 mm thick, 20 mm lugs, Sellita SW200-2 no-date with a stated 65-hour reserve, 200 m, double-domed sapphire, a 120-click bezel with a sapphire insert in an elapsed-time or 12-hour scale, Globolight markers. $970 adds the titanium bracelet; the 40 mm fixed-bezel version is $765. Assembled in Vancouver, 24-month warranty, sold in batches paid in full at order; the batch was closed on the check date with delivery estimated for late December 2026 or early January 2027. For $70 more the Tissot is buyable today with a dealer behind it and 300 m. The Halios guide explains the cycle.

$875 buys the one watch here with a dealer network and the only 80-hour reserve. Powermatic 80 in the 40 mm case introduced in 2024, 12.48 mm thick, 20 mm lugs, 300 m, sapphire with AR underneath, a unidirectional steel bezel with a mineral glass insert, a bracelet with a folding clasp and quick release. Tissot does not publish a lug-to-lug, the only blank in that column on the page, so measure before ordering. The 43 mm at $925 gets a ceramic insert. Against the Halios $70 below, this is 300 m and in stock against titanium and a sapphire insert. From here the ladder jumps $975 to the first chronometer.

$1,850 buys the first COSC certificate on the ladder, on a Soprod M100 in a 39 mm case. 46.5 mm lug-to-lug, 12.2 mm thick, 20 mm lugs, 300 m, a 2 mm double-domed sapphire, a ceramic insert carrying 60-minute, 12-hour and 15-minute countdown scales, C3 lume, a woven steel bracelet with integrated end links. Made in Switzerland per the brand, two-year warranty; the site shows $1,850 to US buyers and €1,590 in Europe. The 5330 with a date is $1,990 and was sold out on the check date. For $235 more the Formex is 1 mm shorter and 1.2 mm thinner with the same certificate; this one has the bracelet and the countdown scale. The Serica guide has the field chronometers from $1,290.

$2,085 buys the shortest lug-to-lug on the page at any price, 45.5 mm, with a COSC Sellita SW300-1 inside. 39.5 mm case, 11 mm thick, 22 mm lugs, 300 m, sapphire with AR, a 120-click bezel with an interchangeable zirconium oxide ceramic insert, BGW9, on rubber or a screwed-link bracelet with a carbon fibre composite clasp and micro-adjustment. Formex has been in Biel since 1999; the store's own dollar pricing runs $2,085 to $2,230 by strap (CHF 1,760 to 1,890), with a three-year warranty. The 42 mm Reef is the same money and the Reef GMT $2,355. Against the Serica $235 below, this is the shorter, thinner watch; against the Monta $465 above, it is the certified one. The Formex guide has the Essence line.

$2,550, the top rung, buys a bigger watch rather than a certified one. Monta's Oceanking: 40.5 mm, 48 mm lug-to-lug, 12 mm thick, 20 mm lugs, Caliber M-22 on a Sellita SW300 base, 300 m, a flat bevelled sapphire with seven-layer AR underneath, a 120-click lumed ceramic bezel, BGW9. The aluminium-bezel version is the same price. What the $465 over the Formex buys, on paper, is 2.5 mm of lug-to-lug (48 mm against 45.5 mm) and a movement without the COSC certificate the Formex and Serica carry; whatever else it buys is not on the spec sheet, and this site does not guess. Monta's Triumph field watch at $1,850 is on the field list.

Buy the Mako II at Orient USA's $285 and treat the $465 list as a formality; the maker's store showed the lower figure in stock on the check date. 41.5 mm, 13 mm thick, 22 mm lugs, Orient F6922, 200 m, a 120-click bezel, mineral crystal. Lug-to-lug is not published, which on a 41.5 mm diver is the figure you most want. For $349 the Islander 42 mm on the ladder adds sapphire and a day-date; for $285 nothing else here is an automatic diver. The crystal is the trade, and the Ray II is the same watch with a different dial.

The Ray II is the Mako II with a different dial, and at $290 on Orient USA's site against a $465 list it is the same decision. 41.5 mm, 13 mm thick, 22 mm lugs, Orient F69, 200 m, a 120-click bezel, hardened mineral crystal; in stock at the maker on the check date. Orient publishes no lug-to-lug for either. The alternative for the money is the San Martin 6200 at $275 on the ladder, a 38 mm case with sapphire, a ceramic bezel and a Dongguan address. Choose between a dealer network with mineral glass and a direct seller with sapphire; the money is the same.

The SNE589 is the Seiko to buy if the movement can be solar: $525 at list buys ISO 6425 certification, sapphire and the thinnest case in this band at 10.7 mm. 42.8 mm across, 49.2 mm lug-to-lug, 20 mm lugs, V157 solar quartz, 200 m. The list price is Long Island Watch's, because the Seiko USA page was gone on the check date; the retailer showed $420 and sold out. For $50 more the Citizen NY0158 is the mechanical alternative with the same ISO wording; for $75 less the Citizen BN0150 on the ladder is solar on mineral glass. The trade is length: 49.2 mm is a long watch.

The SRPE93 is the Turtle without the King's sapphire and ceramic, and $525 against $650 is the price of the difference. 45 mm, 13.42 mm thick, 22 mm lugs, 4R36 with hand-winding, 200 m, a 120-click bezel with a lumed pip, Hardlex, on silicone. Seiko USA and Long Island Watch both showed it sold out on the check date, and the retailer's price was $420. The $125 to the SRPE03 buys sapphire, a ceramic insert and the date magnifier on the same case; the King Turtle is the better buy unless Hardlex is something you can live with. Seiko does not publish the lug-to-lug.

The NY0158 is the mechanical ISO diver at $575, successor to the NY0040 the older lists still name and Citizen's US site no longer carries. 44 mm, 20 mm lugs, Citizen 8204 automatic, 200 m, sapphire with AR, a screw-down crown, ISO compliance stated by the maker, black-coated steel with a dark blue bezel. Sold out on citizenwatch.com on the check date; no thickness or lug-to-lug is published. For $75 more the Seiko King Turtle on the ladder gives the same ISO wording with a ceramic insert and a case Seiko measures. Against the SNE589 at $50 less, the trade is a mechanical movement for a case nobody has measured.

The Hydra SIII is the Lorier diver with a true GMT, and Lorier no longer sells it: the product page returns a 404 and the 2026 relaunch did not include it. Recorded at the $599 it was reviewed at in August 2023. 41 mm, 46 mm lug-to-lug, 12.2 mm thick, 20 mm lugs, Miyota 9075, 200 m, a rotating dive bezel, domed acrylic, on a steel bracelet. The 46 mm lug-to-lug on a 41 mm case is the Lorier habit and the reason to want one. For $100 more the Neptune on the ladder is the current watch with sapphire and no second zone; the Hydra needs the second-hand market.

The Puck II is 48 mm of lugless steel rated to 500 m, and Halios was not selling it on the check date. Recorded at the $675 plus shipping quoted at the 2020 prototype stage. 48 mm across, 14 mm thick, Miyota 9015, 500 m, double-domed sapphire with AR beneath, a rotating bezel under a sapphire overlay, C3 lume, on a steel bracelet. No lug width or lug-to-lug in the data. The Nodus Sector Deep on the ladder is the same 500 m for $25 less in a 38 mm case, and was at least listed. Wait for the batch or buy it used.

The Avalon II is the Nodus diver for a wrist the Sector Deep is too small for, and it is not in the current catalogue. Recorded at $700 from its March 2022 launch coverage. 43.5 mm, 48 mm lug-to-lug, 12.75 mm thick, 20 mm lugs, Miyota 9015, 300 m, double-domed sapphire, a 120-click bezel with a glossy ceramic insert, an H-link bracelet tapering 20 to 18 mm with the NodeX clasp. The 48 mm lug-to-lug on a 43.5 mm case is short for the diameter. For $50 less the Sector Deep is the Nodus you can put on a waiting list; the Avalon needs a used listing.

The Devil Diver is a $795 watch the discounters sell for $345, and the gap tells you what the list price is worth. 44 mm, 15 mm thick, the thickest in this band, 22 mm lugs, a Bulova automatic on a Miyota base with 24 jewels, 200 m, a box sapphire, a unidirectional black and red bezel. Jomashop showed $345 and out of stock on the check date; bulova.com could not be reached. No lug-to-lug is published. For $650 the Seiko King Turtle on the ladder has an ISO rating and a maker that answers; at $345 the Bulova is far cheaper, if you can find one.

The 43 mm Seastar is the 40 mm on the ladder with $50 added and a ceramic insert in the bezel, which is the whole difference. 43 mm, 12.7 mm thick, 21 mm lugs, Powermatic 80 with the 80-hour reserve, 300 m, sapphire with AR beneath, a unidirectional bezel with a ceramic insert, 316L steel. Tissot publishes no lug-to-lug for either size. For $875 the 40 mm gives up the ceramic and keeps everything else. For $925 nothing else here has both a dealer network and 300 m; the Certina 40.5 mm below is the closer rival, same movement, priced in francs.

The Orient Star Sports Diver is an ISO 6425 automatic with a power reserve indicator, and Orient USA sells it for $700 against a $1,170 compare-at, sold out on the check date. 43.6 mm, 51 mm lug-to-lug, 14 mm thick, 20 mm lugs, Orient F6N47 with a 50-hour reserve, 200 m, sapphire with AR, a 120-click bezel. The 51 mm lug-to-lug is the longest figure on this page apart from the Tudor FXD, and it decides the matter. For $1,320 the Christopher Ward 40 mm is 47.45 mm with 300 m and a Sellita; for $700 the Orient is the bargain if the case fits.

At $1,320 the 40 mm Trident is the reference Christopher Ward diver and the size the range is built around. 40 mm, 47.45 mm lug-to-lug, 11.3 mm thick, 20 mm lugs, Sellita SW200-1, 300 m, sapphire with AR, a 120-click bezel with a ceramic insert, Grade X1 lume, on bracelet. The maker's page showed £960 and pre-order on the check date; the dollar figure is what the site shows with its currency set to the United States. For the same $1,320 the 42 mm is 49.3 mm long; for $55 more the 38 mm is 45 mm. The Serica at $1,850 adds a COSC certificate.

The 42 mm Trident is the same $1,320 as the 40 mm and was the one in stock on the check date, a fact worth the entry for a pre-order brand. 42 mm, 49.3 mm lug-to-lug, 11.5 mm thick, 22 mm lugs, Sellita SW200-1, 300 m, sapphire with AR, a 120-click bezel with a ceramic insert, Grade X1 lume, on bracelet, £960 on the maker's page. Against the 40 mm it is 1.85 mm longer and 0.2 mm thicker for the same money. Buy it for the wrist that finds 47.45 mm short, or because it ships.

The 38 mm Trident is the shortest Christopher Ward diver at 45 mm lug-to-lug, and the dearest of the three at $1,375, £1,000 on the maker's page, on pre-order. 38 mm, 11 mm thick, 20 mm lugs, Sellita SW200-1, 300 m, sapphire with AR, a 120-click bezel with a ceramic insert, on bracelet. The $55 over the 40 mm buys 2.45 mm less length and 0.3 mm less thickness, a fair rate. The Formex Reef 39.5 on the ladder is 0.5 mm longer and $710 more, with a COSC Sellita; the Ming 37.09 at 44.5 mm below has no price. For a small wrist this is the buyable one.

The SUB 300T is the deepest rating on the page by a factor of two, 1,200 m, at $2,190 on a steel bracelet. 42.5 mm, 13.65 mm thick, 20 mm lugs, a Swiss automatic with a 38-hour reserve that Doxa does not name on the page, sapphire with AR, a unidirectional bezel carrying the no-decompression scale in feet. Doxa publishes no lug-to-lug. Against the Formex Reef on the ladder, $105 less, this is 900 m more water resistance and a movement without a certificate or a name; the Formex is 2.65 mm thinner. Buy the 300T for the rating and the bezel, not the sheet.

The same Aquis Date reference, recorded from a second reading of Oris's US page, which gave the price as $2,600 and the status as not available. The data holds two rows for one reference and this one carries figures the first does not, so both stand. Caliber 733-1 at 28,800 vph with a 41-hour reserve, 41.5 mm, 22 mm lugs, 300 m, sapphire domed both sides, a ceramic insert. A search snippet showed $2,800 for the ref; the maker's page said $2,600, and the maker's figure stands. The 41-hour reserve is what the other row lacks, and against the 72 hours of the Longines $250 up it is the trade.

The Divers Sixty-Five 40 mm is $2,600 on rubber and rated to 100 m, the lowest rating on the page, below the $85 Casio's 200 m. 40 mm, 20 mm lugs, Oris Caliber 733, sapphire domed both sides with AR inside, a unidirectional bezel with the minute scale on the top ring. No thickness or lug-to-lug is stated. For the same $2,600 the Aquis Date is 300 m and ceramic; the Calibre 400 version in 38 mm at $4,100 is on the under-$5,000 list. 100 m is its honest figure.

The Legend Diver 42 mm in blue on leather is $2,850 on the Longines US e-shop, and it is the super-compressor here: an internal flange turned by a second crown. 42 mm, 300 m, Longines L888 with a silicon balance spring and a 72-hour reserve, sapphire with multi-layer AR beneath. Longines publishes no thickness or lug-to-lug. For $650 more the 39 mm is the same idea in the smaller case; for $250 less the Oris Aquis is a conventional bezel with a shorter reserve. The internal bezel is the reason to buy it and the reason not to.

The same SLA079 as recorded from Seiko's US Marinemaster listing, where the row is worth keeping for what sits beside it. The listing shows the SLA077 and SLA079 at $2,900, the SJE099, SJE101, SJE117 and SJE119 at $2,800, and the 2026 HBF001 and HBF002 on the 8L45 at $3,600 and $3,900. This row adds the lug width, 20 mm, that the other omits; the rest agrees: 42.6 mm, 49.3 mm lug-to-lug, 13.4 mm, 8L35, 300 m. For $100 less the SJE line is the slimmer Marinemaster; for $700 more the 8L45 is the new movement. The SLA079 is the middle of its own family.

The U50 is 500 m in 11.2 mm of German submarine steel, and none of it could be read from Sinn's own site, which blocked every fetch. $3,440 on silicone and $3,640 on the H-link bracelet are WatchBuys search-snippet figures; 41 mm, 11.2 mm thick, Sellita SW300-1, sapphire and a captive Tegimented bezel are from sinn.de snippets. No lug width or lug-to-lug. Against the Doxa SUB 300T at $1,250 less this is 700 m shallower and 2.45 mm thinner; against the Tudor Pelagos 39 at $2,185 more it is steel against titanium. The silicone-strap U50 is also on the under-$5,000 list. Verify the price before you rely on it.

The 39 mm Legend Diver is $3,500 on the Longines US site, $650 more than the 42 mm, the wrong way round on paper and the right way round for a small wrist. 39 mm, 300 m, an automatic at 25,200 vph with a silicon balance spring and 72 hours, sapphire with AR on both sides, the internal rotating flange, on leather. No thickness or lug-to-lug for either size. For $3,500 the TAG Heuer Aquaracer 43 mm is the conventional bezel in a bigger case; for $2,850 the 42 mm is the same watch with 3 mm more. Pay the $650 for the size or do not; nothing else changes.

The Aquaracer Professional 300 in 43 mm is $3,500 at Shreve, Crump & Low, an authorised dealer, because TAG Heuer's own page did not give up a price. 43 mm, 300 m, TAG Heuer Calibre 5, sapphire, a unidirectional steel bezel with a ceramic insert, on bracelet. The dealer's page says 40 mm in its body and 43 mm in its title; The 1916 Company says 43 mm, which is recorded. No thickness or lug-to-lug. For the same $3,500 the Longines 39 mm is 4 mm smaller with a 72-hour reserve; for $60 less the Sinn U50 is 500 m.

$4,600 buys the Captain Cook in high-tech ceramic, a monobloc case with steel and titanium PVD elements, the only ceramic case on the page. 43 mm, 14.6 mm thick, Rado R734 with a Nivachron hairspring and an 80-hour reserve, a rotating ceramic bezel with Super-LumiNova details. Rado's page gave no water resistance, crystal or lug width. For $2,100 less the steel 39 mm Captain Cook is the same family; for $425 more the Tudor FXD is titanium with a stated 52 mm lug-to-lug and a COSC certificate. Buy the ceramic for the material, not the sheet.

The Pelagos FXD is the rare Tudor with a stated lug-to-lug, 52 mm, and it is the longest figure on the page. $5,025 on the fabric strap at Exquisite Timepieces, a US authorised dealer, because Tudor's site prices by location. 42 mm, 12.75 mm thick (Tudor also prints 12.8), 22 mm lugs with fixed bars, MT5602 with a COSC certificate and 70 hours, 200 m, sapphire, a bidirectional titanium bezel with a ceramic disc. Fixed bars mean straps only. For $300 more the Black Bay 41 is steel with METAS; for $600 more the Pelagos 39 is the titanium diver with lugs. Measure 52 mm before ordering.

The Black Bay 41 is the current METAS-certified Tudor, $5,325 on bracelet and $5,075 on rubber at Exquisite Timepieces, a US authorised dealer. 41 mm, 13.6 mm thick, 21 mm lugs, MT5602-U with COSC and METAS certification and a 70-hour reserve, 200 m, domed sapphire, a unidirectional bezel with a black aluminium insert, steel. Tudor gives no lug-to-lug for this one. For $300 more the Pelagos 39 is titanium and 1.8 mm thinner; for $2,675 more the Omega Seamaster 300 is the other Master Chronometer here. The Black Bay 58 at $5,350 on the under-$10,000 list is the 39 mm case for $25 more.

The Pelagos 39 is the titanium Tudor with lugs, $5,625 at Exquisite Timepieces, a US authorised dealer, and the thinnest watch over $5,000 here at 11.8 mm. 39 mm, 21 mm lugs, MT5400 with a COSC certificate and about 70 hours, 200 m, sapphire, a unidirectional grade 2 titanium bezel with a ceramic insert, monobloc ceramic-composite hour markers. No lug-to-lug from Tudor. For $600 less the FXD is titanium at 42 mm with fixed bars and a stated 52 mm length; for $300 less the Black Bay 41 is steel with METAS. Against the Laventure Marine Type 3 at CHF 4,200, this is the one you can order.

$8,000 on Omega's US page buys the Seamaster 300 Heritage in 41 mm on a bracelet, a Master Chronometer on the 8912 Co-Axial with METAS certification, the only Omega on this page. 41 mm, 300 m, sapphire, a unidirectional aluminium bezel with vintage-toned Super-LumiNova, 316L steel. Omega's technical tab, with thickness and the between-lugs figure, was not in the fetched page. For $2,375 less the Tudor Pelagos 39 is titanium with a COSC certificate and 200 m; for $3,350 more the Rolex Submariner is the other 41 mm. The Seamaster Diver 300M in 42 mm at $6,700 sits on the under-$10,000 list.

The Submariner Date is $11,350 at list on rolex.com, the top of this page by $3,350, and list is the number the dealers do not sell at. 41 mm, 300 m, calibre 3235 with about 70 hours and the Superlative Chronometer designation, sapphire with the Cyclops, a unidirectional Cerachrom bezel with platinum-coated graduations, Oystersteel. Rolex publishes neither thickness nor lug-to-lug. For $3,350 less the Omega Seamaster 300 is the certified alternative you can buy at the price printed; for $5,725 less the Tudor Pelagos 39 is titanium with a COSC certificate. The list price is where the queue starts.

The Ocean One 39 is €740 including German VAT on Steinhart's site, €621.85 without it, which is what a US buyer pays before duties, and it was in stock on the check date. 39 mm, 46.78 mm lug-to-lug, 12.5 mm thick, 20 mm lugs, Sellita SW200-1 in Elaboré grade with hacking, 300 m, medium-domed sapphire with double AR inside, a unidirectional bezel with a black ceramic insert. Steinhart has no dollar storefront. For $735 the Traska on the ladder is a hardened case with a three-year warranty; the Steinhart is the Swiss movement at 300 m.

The DS Action Diver 38 mm is CHF 790 on certina.com with no US storefront, so it is here in francs, placed between the Tissot 43 mm and the Certina 40.5 mm by the rate. 38 mm, 13.22 mm thick, 19 mm lugs, Powermatic 80.611 with the 80-hour reserve, 300 m, sapphire with AR on one side, a unidirectional steel bezel with a ceramic insert, BGW9, ISO 6425:2018 stated by the maker. The 19 mm lug width is the odd figure; no lug-to-lug. It is the Tissot Seastar's movement in a smaller case with an ISO line the Tissot lacks; the price moves with the rate.

The 40.5 mm DS Action Diver is CHF 835, CHF 45 over the 38 mm, and it is the size that replaces the 43 mm Certina no longer lists. 40.5 mm, 14.1 mm thick, 20 mm lugs, Powermatic 80.611, 300 m, sapphire with AR on one side, a unidirectional steel and ceramic bezel, BGW9, ISO 6425:2018. The 14.1 mm thickness is the figure against it: 0.88 mm over the 38 mm and 1.4 mm over the Tissot Seastar 43 mm on the same movement. The Tissot at $925 is the dollar-priced route to the Powermatic 80; the Certina is the ISO wording and a smaller case.

The 1521 is 500 m in a 42 mm case for CHF 1,178 on squale.ch, and the rate puts it between the Christopher Ward 38 mm and the Doxa. 42 mm, 48 mm lug-to-lug, 12.5 mm thick, 20 mm lugs, Sellita SW200-1 with a 38-hour reserve, flat sapphire with AR, a unidirectional bezel, C3 lume, on rubber, available on the check date. The 48 mm lug-to-lug matches the Traska and the Monta. The 500 m rating is the reason to buy it over the Christopher Ward 42 mm, which is 300 m at 49.3 mm; the 38-hour reserve is what you give up against every Powermatic here.

The M60 AquaLion is £2,375 before VAT (£2,850 with it) on Vertex's site, and it was sold out on the check date. 40 mm, 48.9 mm lug-to-lug, 14 mm thick, 20 mm lugs, Sellita SW300-1 with a COSC certificate and 56 hours, 600 m, a double-domed box sapphire, a matte ceramic bezel with the scale in Grade X1, ISO 6425 stated, a bracelet and two straps in the box. The rate places it between the Longines 42 mm and the Sinn. 14 mm and 48.9 mm are the cost of the rating. The Sinn U50 is 500 m at 11.2 mm.

The Marine Type 3 is CHF 4,200 before taxes, 100 pieces for 2026 in black or white, and sold out on the check date. 38 mm, 46.2 mm lug-to-lug, 11.2 mm thick (8.9 mm before the crystal), stonewashed grade 23 titanium, Laventure Caliber 4 on a Sellita SW300-1 base with a COSC certificate and 56 hours, 300 m, a fixed bezel, a chimney-shaped plexiglass crystal. Dimensions are Monochrome's, June 2025. The rate places it above the Tudor FXD. Against the Pelagos 39 at $5,625 it is 0.6 mm thinner and 1 mm smaller, with plexiglass for sapphire and no bezel to turn; that is the whole argument, both ways.

The DS PH200M is the Certina worth wanting and the one Certina has stopped selling: certina.com marks the reference no longer available and the maker showed no price on the check date. The last provenance is that page, read on 20 September, with no archive figure. 42.8 mm, 11.9 mm thick, 20 mm lugs, Powermatic 80.611 with 80 hours, 200 m, sapphire with AR on one side, a unidirectional bezel with a ceramic insert; the hesalite C036.407.11.280.00 at 12.9 mm is retired with it. At 11.9 mm it is 2.2 mm thinner than the 40.5 mm DS Action Diver that replaces it.

The Sous-Marine II is 99 pieces, sold out, and the maker showed no price on the check date; the last provenance is the Steel/Cream product page, sold out, with the bronze variant sold out beside it. 40.5 mm, 48.8 mm lug-to-lug, 9.9 mm before the superdomed plexiglass, Laventure Caliber 2 built by Chronode at 4 Hz with a 60-hour reserve, 200 m, a 120-click unidirectional bezel, a sapphire display back, 316L. At 9.9 mm before the crystal it is the thinnest case figure on the page; the Lorier Neptune's 10.3 mm on the ladder is the nearest, and is buyable. A watch to know about, not to plan on.

The 37.09 Bluefin is sold out with deliveries complete and Ming says it will not be made again; the price has been removed from the page, and the maker showed no price on the check date. The last provenance is the archive page read on 20 September, no figure; a snippet's CHF 4,950 is not adopted. 38 mm, 44.5 mm lug-to-lug, the shortest on the page, 12.8 mm thick, 20 mm lugs, Sellita SW300.M1 for Ming with about 50 hours, 600 m, domed sapphire front and back with double AR. Nothing buyable here is 600 m at 44.5 mm; the Vertex is 600 m at 48.9 mm.

The 37.09 Uni is the Bluefin's case in matte-brushed DLC, and it is the same story: sold out, deliveries complete, not to be produced again, and the maker showed no price on the check date. The last provenance is the product page read on 20 September, price slot empty; Ming's home page had called it in stock the day before. 38 mm, 44.5 mm lug-to-lug, 12.8 mm thick, 20 mm lugs, 600 m, Sellita SW300.M1, domed sapphire both sides with the indices lumed in Grade X1 under the crystal, a fixed bezel, moulded FKM rubber on a tuck buckle. The Bluefin is the steel version; neither is orderable.

The SPB143 is discontinued: the Seiko USA and Seiko Luxe pages return 404, the authorised dealer Feldmar marks it discontinued, and the maker showed no price on the check date. The last provenance is seikoluxe.com on 20 September, a 404 with no archive figure; the $1,200 list the search snippets remember is unverified on any maker page and is not adopted. 40.5 mm, 200 m, 6R35, curved sapphire with AR, LumiBrite, steel with Seiko's super-hard coating. Lug-to-lug and thickness are not in the data. The successor is the SPB453 at 300 m with a three-day reserve; the SPB317 slim 62MAS at $900, which is buyable, sits on the under-$1,500 list.

The Modello Cinque in the MoMA edition is 75 pieces, mostly sold out, and the maker showed no price on the check date: the Shopify feed returns a variant price of zero, which is what Unimatic does after a sell-out. The last provenance is that feed, read on 20 September. 36 mm, 11.05 mm thick, 300 m, Sellita SW200-1 with 38 hours, double-domed sapphire with AR, a black compass aluminium insert with silver trims, C1 lume, two straps in the box. At 36 mm it is the smallest diver on the page by 2 mm. The UC1 at $760 on the under-$1,000 dive list is the Unimatic you can order.
