Unimatic's quartz Modello Uno, the dive watch of its permanent Toolwatch collection, launched in July 2024 with the UT1-GMT, UT4 and UT4-GMT (Fratello): the Modello Uno case in sandblasted steel with a flat crystal, on a Seiko VH31A sweeping-seconds quartz held in Unimatic's '360° protection system' (a TPU gasket above the dial and a TPU movement holder), which Unimatic says is certified to MIL-STD-810H. The UT1 itself is in regular production; numbered limited editions on the same case are recorded as variants. The UT1-GMT, on a Ronda 515.24D, is a separate model. Common specification, from Unimatic's UT1 spec sheet: 40mm case, 41.5mm across the bezel (recorded as the diameter), 49mm lug to lug, 13.2mm without the crystal and 13.6mm with it (Fratello quotes 13.2mm), 28.4mm case opening, 22mm lugs, 316L steel, 8mm screw-down crown, screw-in caseback, individually tested to 300m, 120-click mono-directional bezel, 2.5mm flat sapphire with anti-reflective coating on the inner side, 80g head and 95g on the strap. Unimatic names the VH31A with 2 jewels, ±15 s/month and about two years on an SR920SW cell; the movement file describes the current VH31B. Prices are Unimatic's euro prices for Italy, VAT included. The UT1 is also sold as a 'Bracelet Premium Set' (ref. UT1-UBR) with Unimatic's UBR-TLQ18 sandblasted steel bracelet with integrated quick-release, the nylon strap and a tough case instead of the travel pouch, recorded as a second price for the UT1; no clasp details are published. Edition details. UT1-AS and UT1-GO (2025, 300 each): Alpine sky blue or glacier white dial with hand-applied 3D UNILIGHT C1 markers, steel hands, Italian Alps caseback, fumo deer leather strap; the photos show a minimal insert with a lume dot where the sheets, apparently copied from the UT1's, say countdown, minimal recorded; their sheets give 81g head and 94g on the strap. UT1-BSTN (2025, 50) was made with BSTN: brushed instead of sandblasted case, black anodised aluminium diving insert, BSTN logo at 3 and 'Built Different' at 12, pink trims and seconds hand, 'A decade strong' caseback. UT1-IPN, UT1-IPP and UT1-IPT (2026, 99 each, Swimming Pool Collection): crystal blue, infinity mist or acqua laguna dial with hand-applied 3D UNILIGHT C1 markers, deep blue insert and TPU strap, Swimming Pool caseback; their sheets and descriptions say countdown insert, but the product renders and wrist photos show a minimal insert with a lume dot, minimal recorded; their sheets give 81g head and 101g on the strap. UT1-PD (2026, 250) joins the Toolwatch and ProDiver lines: the photos show a 60-minute diving insert counting up, with an orange triangle, and a dot-and-baton dial, where its spec sheet, apparently copied from the UT1's, says countdown insert and printed Arabic numerals (the description also says countdown), photos recorded; its sheet gives a 3mm crystal, 13.3mm without and 13.6mm with it, 81g head and 99g on the strap; ProDiver dive-mask caseback, black TPU strap; the page has no year tag, so the year is from Acquire's launch report (August 2026).
