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

The Modello Quattro U4S in titanium, 65g for the head against 98g for the steel U4S, on the same Sellita SW200-1 b, sold as numbered limited editions, each recorded as a variant; the titanium U4S-T-HS on the ETA 2893-2 is the separate Modello Quattro U4S Titanium GMT. Common specification, from Unimatic's sheets for the U4S-T-LB (2026) and U4S-T-SPW (2025): 40mm case, 49mm lug to lug, 28.4mm case opening, 12.7mm thick without the crystal and 13mm with it (recorded; Monochrome also gives 13mm with the crystal, Fratello 12.7mm), 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, 65g for the head (recorded), 78g on the U4S-T-LB's NATO and 76g on the U4S-T-SPW's nylon strap. Grade 2 titanium and the sandblasted finish are from the U4S-T-LB sheet and page; the U4S-T-SPW sheet says only titanium, finished with a bright white Cerakote H140 coating. Unimatic quotes the SW200-1 b (SW200-1 a on the U4S-T-SPW sheet, b in its description) at +/-12 s/day with at least 38h of power reserve (typically 41h), without naming a grade or claiming regulation. Neither edition 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. Edition details. U4S-T-LB (2026, 300), still on sale in October 2026: sandblasted case, sandblasted titanium-colour California dial with half Roman, half Arabic numerals, light blue Super-LumiNova, cool grey closed seconds rail and dark grey trims, titanium-colour hands with a cool grey seconds tip, NATO Military Symbols caseback, mint green nylon NATO with sandblasted titanium hardware; its page carries no year tag, and its sheet and Fratello's hands-on date from April 2026. U4S-T-SPW (2025, 60) was made with Massena LAB, the last of their NASA Artemis trilogy after the Modello Uno U1-SPG and the Modello Quattro UT4-SPT: bright white Cerakote H140 coated titanium case, meteorite dial with a Widmanstätten pattern, BG W9 markers and NASA worm logo printed on the crystal, BG W9 hands with a red seconds tip, meteor comparison chart caseback, white nylon keeper quick-release strap plus a cool grey TPU quick-release strap, Cerakote-coated titanium buckles; it was sold only at Geneva Watch Days, 4 to 7 September 2025, at 2,500 EUR before VAT (Monochrome), which is the 3,050 EUR with Italian VAT that its page shows; its page carries no year tag.
