Unimatic Modello Quattro Ultratool UT4-U-TI-GMT

Archive · used only

Unimatic is an Italian maker of pared-back tool watches, and the Ultratool UT4-U-TI-GMT is its travel version in sandblasted Grade 2 titanium, a limited edition of 99 numbered pieces. It runs on a Swiss Ronda 515.24D quartz movement, which shows a second time zone in a window at 12 o'clock and the date at 6, so the dial stays as spare as Unimatic's time-only watches. The case is 40 mm across, 12.3 mm thick and 49 mm lug to lug, individually tested to 300 m, with an 8 mm screw-down crown, a 2.8 mm flat sapphire crystal and Unimatic's shock-protection system, and it carries MIL-STD-810H certification. The head weighs 53 g. It came on a three-layer nylon strap in black and international orange at $840, and the edition has since sold out, so Unimatic now files it in its archive.
