The high-end microbrands, ranked

Fifteen small makers whose current ranges top out between $2,450 and EUR 110,000, ranked on four published facts rather than on price. One representative model per maker, with its spec sheet and the price the maker showed on 19 September 2026; most of the top-range pieces were sold out or on a waitlist that day.

Checked 19 September 2026 · list prices on the maker's site that day unless marked street

Above about $2,000 the word microbrand stops describing a Miyota in a contract case and starts covering workshops that fire their own enamel, commission their own calibres or build one watch at a time to a deposit. The 15 makers below all sell direct, all publish a spec sheet, and all sit above the bracket lists on this site. What separates them is not the price, which runs from $2,450 at Serica to EUR 110,000 at Sartory-Billard, but what the price is paying for.

Price alone would put Atelier Wen (Inflection at HKD 233,900, and HKD 326,300 for the Shuò edition with Massena LAB), Sartory-Billard (SB06 from EUR 110,000 excluding VAT) and Lundis Bleus (Ref. 1125 at CHF 15,800) in the first three places. The ranking does not follow price because two of those three ceilings are dial work and edition size on supplier calibres: the Inflection runs a customised Girard-Perregaux GP03300, the Ref. 1125 a Le Temps Manufacture LTM5000, and both makers' core lines run Pequignet and Sellita. Sartory-Billard stays first because its ceiling is an in-house flying tourbillon, not a dial. Below it, Ophion, Massena LAB, Formex and Ming all commissioned or modified their own movements at prices between EUR 3,975 and $8,675, and the criteria put that above a dearer dial.

Every price is the figure the maker's own site showed on the check date, in the currency it showed. Nothing is converted: an anOrdain is GBP 3,695 plus VAT, a Straum is NOK 33,500, a Ming is CHF 6,250. Several of these makers sell in drops, allocations or build slots, and the entry says so where it applies. Where a maker's own pages disagree with each other, the entry says that too.

How the list was chosen

Four things, weighed in this order. Where two makers tie on the first, the second decides, and so on down.

  • Movement class. A bespoke or in-house calibre or module ranks first: the Sartory-Billard SBTV01 tourbillon, Ophion's Schwarz Etienne ASE 200 micro-rotor, Massena LAB's M660 and M690 designed by Raúl Pagès, the Formex FX01, Ming's customised Sellita calibres. Swiss premium supplier movements (Sellita SW300, La Joux-Perret G100 and G101, Soprod with a COSC certificate) rank second. Miyota and Seiko rank third.
  • Dial and case craft the maker does itself or names the artisan for. anOrdain fires its enamel in its Glasgow factory; Atelier Wen names Cheng Yucai for guilloché and Kong Lingjun for grand feu enamel; Lundis Bleus fires enamel in its Neuchâtel workshop; Fears uses silver dials and a case made in Garrick's Norfolk workshop on its flagship; Zelos machines tantalum. A brand that publishes neither a process nor a name scores nothing here.
  • The price ceiling of the current range, in the currency the maker shows. A sold-out reference still counts if the page still shows a price; Laventure, whose site hides prices when sold out, is left off for that reason.
  • How it is bought. Drops that are not repeated, build slots, deposits and allocation windows are read as scarcity, stated as the maker states them. Stock that sells out counts for less than a queue the maker publishes a date for.

Specs come from the maker's product page or spec sheet, linked under each entry with the check date. A dash means the maker does not publish the figure.

Last, because its ceiling is the lowest here after Serica and it publishes no dial or case process of its own; what it does publish is every dimension. The Oceanking is 40.5 mm, 48 mm lug-to-lug, 12 mm thick, 300 m, with a 120-click ceramic bezel and a 7-layer AR sapphire, $2,550 on the maker's site, on a Caliber M-22 the brand states is a Sellita SW300 base manufactured, assembled and tested in Switzerland. The range is $1,850 (Triumph) to $2,550, about 700 watches a year. The craft claim is the bracelet: quick-adjust clasps designed in-house and a patent-pending bezel assembly. Most references were sold out on the check date. Warranty two years, transferable once. The Serica above at $2,450 is 100 m shallower and carries a certificate.

Considered and left off

Makers considered for this page and left off, with the reason. Laventure (Neuchâtel, series of 50 to 100, a COSC Sellita-based Caliber 4 in grade 23 titanium) hides prices while sold out, which on the check date was everything; the CHF 4,200 and CHF 3,350 figures in the data come from Monochrome and Watch Affinity, not the maker's site, and the criteria need a maker's price. Kurono Tokyo runs Miyota 9122 and 90S5 across the range ($1,850 to $2,700), the third movement class, and the Diver's $2,700 comes from Hypebeast rather than the brand. Schofield makes cases in Britain, including the Vegas Forge Damascus Obscura at GBP 9,558, but its Light One at GBP 2,190 runs a Seiko NH34A, and a Seiko entry tier puts it under the line. Furlan Marri starts at CHF 585 on a Seiko VK64 mecaquartz. Nivada Grenchen reaches $5,000 on restored Valjoux calibres, but its mecaquartz lines start at $530 and it sells through Watches of Switzerland, which is retail, not a microbrand's ordering model. Studio Underd0g (GBP 600 to 1,750, Seagull ST-1901B at the entry), Charlie Paris (EUR 425 to 1,795, Seiko NH34 and mecaquartz), Bravur ($1,195 to $2,600 on Sellita, built to order in Båstad), Brew ($375 to $495 mecaquartz), Autodromo ($450 to $895) and RZE ($279 to $779) have floors or ceilings under the line this page draws. Ophion is on the list, with its price conflict stated in the entry.

Questions people ask

What is the most expensive microbrand watch?

The Sartory-Billard SB06 flying tourbillon, at EUR 110,000 excluding VAT on the maker's site, 24 a year. Next is the Atelier Wen Inflection Shuò with Massena LAB at HKD 326,300 (Massena LAB lists it at $44,100), then the Fears Brunswick Pt at GBP 21,000 ex VAT, the Fears Garrick at GBP 17,500, the Lundis Bleus Ref. 1125 at CHF 15,800 and the Sartory-Billard SB05 at EUR 15,000. Massena LAB's Vianney Halter collaboration reaches $49,900 but is built by Halter.

Are high-end microbrands worth it?

The spec sheets say what the money buys; this site does not test finishing. At $2,450 to $2,550 (Serica, Monta) it buys a COSC Soprod or a Sellita SW300 base, sapphire and a ceramic bezel. At EUR 3,975 to $8,675 (Ophion, Massena LAB, Formex) it buys a micro-rotor or a proprietary hand-wound calibre. At GBP 3,695 to CHF 15,800 (anOrdain, Lundis Bleus) it buys an enamel dial the maker fires itself. Above that the price is edition size, precious metal and a tourbillon. Warranties run from one year (Zelos) to five.

Which high-end microbrands use in-house movements?

Three commissioned a calibre of their own: Sartory-Billard's SBTV01 tourbillon (made with Comblemine), Formex's FX01 micro-rotor (engineered by Horage, COSC) and Massena LAB's M660 and M690 (designed by Raúl Pagès). Fears's Garrick flagship runs Garrick's UT-G04. Ophion buys a Schwarz Etienne ASE 200 for the Vesper and fits its own bridges to a Technotime/Soprod base in the Vélos. Ming customises Sellita calibres; Monta's M-22 is a Sellita SW300 base. Everyone else runs Sellita, La Joux-Perret, Soprod or ETA as supplied.
