About this entry

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

The Modello Quattro U4S in a matte forged carbon case, which Unimatic calls 45% lighter, on the same Sellita SW200-1 b as the steel U4S, sold as numbered limited editions, each recorded as a variant; the carbon's grey pattern differs on each piece. Common specification, from Unimatic's U4S-C-TAB sheet (the only one of these pages to link one): 40mm case, 49mm lug to lug, 28.4mm case opening, 12.7mm thick without the crystal and 13mm with it (recorded), 22mm drilled lugs, fixed monoblock bezel, 8mm screw-down 'Alchemical Sun' crown between crown guards (photos), screw-down caseback, individually tested to 300m, 2.8mm flat sapphire with anti-reflective coating on the inner side, 51g for the head and 66g on the TPU strap. Unimatic quotes the SW200-1 b at +/-12 s/day with at least 38h of power reserve (typically 41h), without naming a grade or claiming regulation. None of the editions shows a date window (photos), so complications are hours, minutes and seconds. 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. Edition details. U4S-C-H (2023, 250) was made with Hodinkee alongside the forged carbon Modello Uno U1S-C-GMT-H, Unimatic's first forged carbon watches: asphalt grey dial with C1 white lume, matching hands, titanium caseback, asphalt grey TPU strap; its description calls the crystal double-domed, but its side photo shows the flat crystal of the C-TAB sheet; the store shows 0, so the price is the 2,200 USD launch price from Esquire (sold through Hodinkee). U4S-C-TAB (2026, 50) was made with the Lake Como powerboat builder Tullio Abbate: matte forged carbon dial with the Tullio Abbate signature, cool grey trims, GL C1 lume, matte black hands with a red seconds tip, Tullio Abbate number 5 caseback, matte black quick-release TPU strap; its page spec list gives a 2.5mm double-domed sapphire, where its sheet and description give the 2.8mm flat one, recorded; it was on pre-order in October 2026, shipping from 27 November.
