The U4S-T-LB is a limited edition of 300 of Unimatic's Modello Quattro, a military-inspired field watch in sandblasted Grade 2 titanium with a fixed monobloc bezel. The dial is the California layout, half Arabic and half Roman numerals, in a titanium-grey finish with light blue Super-LumiNova, a phantom ladder handset and a reverse lollipop seconds hand. The case is 40 mm across, individually tested to 300 m, with an 8 mm screw-down crown and a screw-down caseback engraved with NATO military symbols, and the head weighs 65 g. A Sellita SW200-1 automatic runs it, with no date. It comes on a mint green nylon NATO with signed titanium hardware and lists at $1,660.
