Studio Underd0g is Richard Benc's British brand, the one that sells watermelon and dessert dials on a hand-wound chronograph, and since May 2026 it has assembled every watch in its own Maidenhead workshop. The decision it forces is which movement you are paying for, since the three series share two cases and the price is almost entirely the movement, a Seagull at one end and a Sellita monopusher at the other.

Studio Underd0g launched in 2020 with the watermelon and dessert dials on its 01Series chronograph. Since May 2026 it has had its own workshop and showroom in Maidenhead, The D0ghouse, and the product pages now say 'Assembled fully in-house, by our own team, in Great Britain', with the assembler's initials recorded on each watch's paperwork. It sells direct and through retail partners (Time+Tide among them), with 'Exclusive Access' SKUs listed alongside the standard ones, and it has made collaborations with H. Moser and Massena LAB. Every series is hand-wound, in 316L steel, under sapphire, with Super-LumiNova (C3 on the chronographs, X1 on the 02Series), and there are two cases. The chronographs share a three-part case at 38.5 mm, 44.5 mm lug to lug and a 20 mm lug, rated 50 m; the 02Series is a two-part case at 37.5 mm, 46 mm lug to lug and an 18 mm lug, rated 100 m. The movement is what the price measures, a Seagull ST-1901B made to the brand's spec at $800, a Sellita SW200-2 M Power+ at $1,200 and a Sellita SW510 M monopusher at $2,200; at home the same three are GBP 600, 875 and 1,750 including VAT.
At $800 the 01Series is the mechanical chronograph under $1,000, where Furlan Marri's Mechaquartz at $725 is a Seiko quartz module. At $2,200 the 03Series sits $105 over Farer's Libre Racing Chronograph at $2,095 on the same SW510 family with two pushers, and well under Vertex's MP45 M monopusher at GBP 2,900 before VAT, which makes the Underd0g the cheaper monopusher in either currency. Formex's Field Automatic 40 at $975 runs the 02Series' Sellita base as an automatic, so the $225 the Underd0g asks over it is the sapphire dial and the Maidenhead assembly.
Two practical notes. The store is underd0g.com, since studiounderd0g.com is a placeholder page, and no warranty term was found on the pages read. A fourth listing is off the table. The 02Series 'The Mim0sa' shows $1,300 to US buyers, GBP 1,000 at home, with the Exclusive Access version in stock and the standard one sold out, but its page returned navigation only and the Shopify feed carries no spec block, so no dimension for it is verified; The Manhattan and The Gimlet are in the same series at the same price. It will join the table when the brand publishes a sheet.

Read the table by movement, which is also by price. The 01Series is the Chinese hand-wound chronograph with the watermelon dial; the 02Series is the Swiss three-hander with the sapphire dial layer and the only 100 m rating; the 03Series is the Swiss monopusher and the top of the range. Colour variants are the same price within a series except where the feed says otherwise, and the entry says where.
The mechanical chronograph under $1,000, and the watermelon dial. The Seagull ST-1901B hand-wound is made to the brand's spec, and the 38.5 mm case runs 44.5 mm lug to lug, 1.5 mm shorter than the brand's own three-hander. $800 to US buyers, GBP 600 at home; Classic Cheese is GBP 625 and Burnt Pepper0ni GBP 700. Against the 03Series at $2,200 it is the same case, 0.7 mm thinner, and the $1,400 is the Sellita and the single pusher. Furlan Marri's Mechaquartz is $725 on a Seiko quartz module, which is the trade for the saving.

The top of the range and the one Swiss chronograph, $2,200 to US buyers and GBP 1,750 at home. The Sellita SW510 M is a cam-operated monopusher in Elaboré grade with 63 hours, in the 01Series case at 13.6 mm, 0.7 mm thicker than the Seagull watch. The Champagne & Caviar made with Massena LAB was GBP 1,750 and sold out. Farer's Libre Racing Chronograph is $2,095 on the SW510M at the same 38.5 mm with 100 m, $105 less with two pushers; Vertex's MP45 M is GBP 2,900 before VAT. The Underd0g is the cheaper monopusher in either currency.
Studio Underd0g is for the buyer who wants a hand-wound chronograph with a dial no other brand would put its name to, at 38.5 mm and 44.5 mm lug to lug, which suits a 6.25 to 7 inch wrist and sits short on anything larger. The 02Series at 37.5 mm and 46 mm is the one for a plainer dial and a swim. Look elsewhere if you want an automatic, since all three series are hand-wound and Formex's Field 40 is $975 on the same Sellita base with a rotor; if you want a diver, since 50 to 100 m is the range and Serica's 5303 is $1,850 with 300 m and a certificate; or if you want a warranty term stated on the page, which the pages read did not give and Farer, Serica and Formex do.
Where it sits against the field
At $800 the 01Series has no mechanical rival at its price with a published lug to lug. Furlan Marri's Mechaquartz at $725 and Dan Henry's 1964 at $310 are Seiko quartz modules, and Lorier's Olympia at $999 on a Seiko NE88 automatic is no longer in Lorier's catalogue. At $1,200 the 02Series meets hand-wound field watches from Hamilton and Marathon at $675 and Farer's Marsden at $1,165 on a Sellita SW210-1 at 35 mm, and automatics from Formex at $975 and Serica at $1,290 with a COSC certificate; the Underd0g is the only one with a sapphire dial. At $2,200 the 03Series sits between Baltic's Scalegraph at $1,891.75 and Farer's Libre at $2,095 on the same Sellita SW510 family, below Nivada's Chronomaster at $2,085 on a Landeron 70 only by dint of the monopusher, and well under Massena LAB's Uni-Racer at $3,495 and Vertex's MP45 M at GBP 2,900 before VAT. The high-end ranking starts above it.
