About this entry

73% of key specs known. Missing: thickness, hardening, crown, bracelet offered.

The Modello Uno U1S in sandblasted grade 2 titanium, which Unimatic says is 45% lighter than steel, on the same Sellita SW200-1, sold as numbered limited editions, each recorded as a variant. The 600m U1S-T-ICON editions, the U1S-T-PD6-B ProDiver with a 3mm crystal and the titanium GMTs are separate models. Neither page links a spec sheet. From the descriptions and the launch coverage (Fratello, aBlogtoWatch, Worn & Wound, November 2022): 40mm case, 41.5mm across the bezel (recorded as the diameter), 49mm lug to lug, 22mm drilled lugs, 8mm crown, 2mm screw-in caseback, individually tested to 300m, mono-directional bezel with aluminium insert, double-domed anti-reflective sapphire (side not stated), 62g (Unimatic's descriptions say '62 grams titanium case'; Fratello gives 62g for the watch and, for the titanium GMT, describes Unimatic's case figure as the weight without the strap, so it is recorded as the head). Thickness: aBlogtoWatch and Worn & Wound give 11.6mm and Fratello 11.25mm, none saying whether the crystal is included; Unimatic's 2026 sheets for the U1S case give 11.6mm without the crystal and 12.8mm with it, so no thickness is recorded. Grade 2 titanium is from Fratello and the U1S-T-MP page; the U1S-T-SE page says only titanium. Unimatic quotes the SW200-1 (SW200-1 b on the U1S-T-SE) at 38h power reserve with hacking seconds, without naming a grade or claiming regulation. Prices are the euro prices for Italy, VAT included, still shown on the sold-out product pages. Edition details. U1S-T-MP (2022, 500), launched with the Modello Due U2S-T-MP and the U1S-TGMT: blu notte dial, engraved professional diver insert and straps, BGW9 lume glowing blue, silver graphics, date window at 6 with a matching blue disc (aBlogtoWatch), conversion-scale caseback; the store files it as a collaboration but names no partner; Fratello gave 1,180 EUR before tax at launch. U1S-T-SE (2024, 60) was made with SEASE, the Italian clothing brand: foliage green dial and professional diver insert with C1 lume, red SEASE logo on the dial, UNIMATIC x SEASE Sailing screw-down caseback, foliage green TPU strap plus a Solaro strap; photos show no date window.
