About this entry

87% of key specs known. Missing: hardening, bracelet offered.

The slim, Swiss-movement version of the Modello Uno U1 dive watch: the same outline in a thinner case with drilled lugs, on a Sellita SW200-1 instead of the U1's Seiko NH35A, sold as numbered limited editions, each recorded as a variant. The case first appeared on the 2021 Hodinkee U1-H, which is recorded here; the U1S references followed with Unimatic's S-series in January 2022 (Fratello), which Unimatic calls 10% slimmer. GMT editions (Sellita SW330-2 or ETA 2893-2), the deeper-rated ProDiver 500 and 600 editions (thicker crystal and case) and editions in another case material are separate models. Common specification, from Unimatic's U1S-HS and 2026 U1S-NPB, NPF and NPT spec sheets: 40mm case, 41.5mm across the bezel (recorded as the diameter), 49mm lug to lug, 11.6mm thick without the crystal and 12.8mm with it (the 2026 sheets; the HS sheet gives only 11.6mm, and Fratello gives 11.6mm against 13.6mm for the earlier U1), 28.4mm case opening, 22mm drilled lugs, 316 brushed steel (316L in the U1S-CIT description and the 2026 sheets), 8mm screw-down crown, 2mm screw-down caseback, individually tested to 300m, 120-click mono-directional bezel with aluminium insert (ceramic on the U1S-MD and U1S-PD3), 2.5mm double-domed sapphire with anti-reflective coating on the inner side, 90g for the head and 111g on the Langhe deer leather strap (2026 sheets). Unimatic quotes the SW200-1 (SW200-1 b on the 2023 and later pages) at +/-12 s/day up to +/-30 s/day, 38h power reserve and antimagnetism to 4,800 A/m, without naming a grade or claiming regulation. Only the U1-H, U1S-HS and U1S-NP pages link a spec sheet; the other editions' specs come from their descriptions, which repeat these figures. The U1-H's 2021 sheet gives 11.25mm and a 29mm case opening (Worn & Wound gives 11.8mm), against 11.6mm and 28.4mm on the 2022 sheets; its diameter, lug to lug, drilled lugs, crown, crystal and movement match, and Beyond the Dial measured its GMT sibling at 11.6mm and describes the Hodinkee case as the start of Unimatic's thinner Swiss-movement case, so it is recorded as an edition here rather than as its own model. Lume colour, bezel scale, case coating, date window and straps vary by edition, so complications are left to the movement (SW200-1, date) and the date window is noted per edition where Unimatic states it. Prices are the euro prices for Italy, VAT included, shown on each product page; where the store shows 0 instead, the price comes from launch coverage or is left blank. Edition details. U1-H (2021, 500) was made with Hodinkee and sold through it: Hodinkee grey dial with C1 lume and no date window, charcoal grey professional diver insert, screw-down caseback engraved with a decompression scale signed UNIMATIC x HODINKEE, reversible black TPU strap plus a single-pass NATO; the store shows 0, so the price is the 875 USD launch price from Worn & Wound. U1S-M (2022, 500) and U1S-MN (2022, 400, black DLC case), the first S-series editions: matte black dial without hour markers, C1-lumed logotype and hands, calf leather strap plus seatbelt NATO; Fratello gave launch prices of 910 and 1,010 EUR before tax. U1S-MP (2022, 500) and U1S-MPN (2022, 400, black DLC case): engraved professional diver insert, C1 lume, date window at 6; the store files them as collaborations but names no partner, and their casebacks carry the standard conversion scale. U1S-MB (2022, 500): mocha brown dial and insert, old radium lume, brown suede strap. U1S-FAI (2022, 200) was made in support of FAI, the National Trust for Italy: galvanic black dial with hand-applied C1 lume, FAI green insert, 'Unimatic sostiene FAI' caseback. U1S-HS (2022, 100) and U1S-HS2 (2023, 100) were made with Highsnobiety and Disney: silver grené dials printed with Fantasia artwork (U1S-HS, BGW9 lume, red lume dot) and Mickey Mouse (U1S-HS2, C1 lume); the U1S-HS2 description is copied from the U1S-HS and describes the Fantasia dial and a red lume dot, where its page header and photos show the 2023 Mickey Mouse dial and a white lume dot, recorded. U1S-ET (2023, 100, black DLC case) was made with Florida retailer Exquisite Timepieces and sold only through it: dark orange lumed minute hand and lume dot, engraved diver insert; the store shows 0, so the price is the 1,150 USD launch price from Fratello. U1S-8B, U1S-8N and U1S-8O (2023, 400 each): black, vintage navy or olive drab dial with matching minimal insert, GL light old radium lume, gold metallic hands, TPU strap plus seatbelt NATO. U1S-8BB (2024, 99, black DLC case), their all-black version: its description mentions a flat sapphire crystal and matte black hands, but its photos show the gold-coloured hands of the other 8 editions and nothing else suggests a different case or crystal, so it is recorded here; its crystal shape is unconfirmed. U1S-CIT (2024, 80) was made with Club Italia: blue heavy grené dial with the club's logo, blue 15-minute insert, caseback engraved with the owner's name; the store shows 0 and no launch price was found, so no price is recorded. U1S-MD (2025, 99), 'The Black Diver': black DLC case (from photos) on Unimatic's first black DLC steel bracelet, lumed matte black ceramic diving insert, BGW9 lume with OL orange accents; photos show a date window at 6; its page quotes 1,350 EUR + VAT and shows 1,650 EUR. U1S-PD3 (2023, 500), the 300m ProDiver launched with the 500m U1S-PD5 (a separate model): matte black dial with white Super-LumiNova glowing orange on the markers, hour hand and seconds tip and BGW9 on the minute hand, Unimatic's first lume-infused ceramic 60-minute insert, a redesigned crown tube with a locking system, charcoal grey TPU strap plus seatbelt NATO; photos show no date window; Fratello and Worn & Wound gave 1,100 EUR before tax at launch. U1S-REV (2023, 200), 'Milsub Blue', was made with Revolution: cerulean blue stonewashed Cerakote case, matte vintage navy outline dial with BGW9 markers, matte white hands, vintage navy aluminium diving insert, vintage navy nylon strap plus TPU strap; photos show no date window; the store shows 0 and no launch price was found (a US retailer lists 1,220 USD), so no price is recorded. U1S-NPB, U1S-NPF and U1S-NPT (2026, 200 each), the Langhe Collection: satin moss, fog or truffle dial with C1 lume, colour-matched anodized aluminium insert, brushed steel hands, cool grey trims, Langhe caseback, deer leather quick-release strap; their sheets list no date window and the photos show none; the store carries no year tag, and they were listed in October 2026.
