U3S-HS

The Modello Tre ref. U3S-HS, marks UNIMATIC’s first series equipped with automatic chronograph caliber. It features a Henry Singer gray dial, concentric circles subdials with markers in Super-LumiNova® white with custom OL Orange emission, matching the dot on the Henry Singer gray ceramic diving insert with Super-LumiNova® BGW09 white markers.

The solid 316L stainless steel case with a brushed finish, the screw-down sapphire exhibition caseback, the 8 mm diameter crown coupled with fat 5.5 mm screw-in pushers, together with the high quality gaskets set provide a water resistance individually tested and certified to 30atm≈300m≈1000ft.

Timing accuracy is powered by the automatic Sellita SW510 BH b movement, operating at 28,800 bph, with a 62-hour power reserve and a hacking seconds hand. The caliber features a second’s indicator at 9 o’clock and 30 minutes counter at 3 o’clock.

The watch comes on a brush solid steel bracelet and an extra shitake gray quick-release leather bump two-piece strap with stainless steel brushed hardware signed UNIMATIC.
