Unimatic Modello Tre U3S-T-AA (x Automobili Amos x Sease)

Unimatic calls the U3S-T-AA its first automatic chronograph in titanium. It was made with Automobili Amos, the restomod car builder, for the Italian clothing brand Sease, which sells the edition of 30. The sandblasted Grade 2 titanium case is 40 mm across, 41.5 mm at its 120-click bezel and 51.2 mm from lug to lug, and Sease gives the head as 77 g. Inside is a Sellita SW510 BH b, rated by Unimatic at a minimum of 56 hours of reserve and typically 62, and visible through a sapphire caseback. The titanium-grey dial carries two subdials, a tachymeter scale and dark orange Super-LumiNova, the oversized chronograph pushers screw down, and the watch is rated to 300 m. It comes on a safari orange TPU strap with a second Solaro fabric strap lined in leather, and Sease still takes orders for it at EUR 4,510.
