The Made in Italy chrono-diver watch, built with a 300M diving grade water resistance. It features a two-eyed black matte dial with Super-LumiNova® C1 white, silver dial trims and a black aluminium professional diver insert with raised lume dot.

The case design blends iconic references with neat technical solutions to offer both performances and a complete aesthetic experience: the recessed caseback and the oversized screw-down chrono pushers meet the most comfortable and curved case ever made by Unimatic, combining our signature vintage dimension with a bold presence on the wrist.


The diving capability of the watch are underlined by the 60 minutes professional diver bezel in black aluminium.

Modello Tre ref. U3-F is the latest addition to our product range, a Made in Italy chrono-diver. It features a two-eyes black matte dial with retro sized marker in Super-LumiNova® C1 white matching the pearl on the black aluminium professional diver insert, silver second rail and graphic trims.

Time is indicated thanks to matching phantom ladder hands set and the black reverse lollipop second hand with white tip. The 2.5mm thick double domed anti-reflective sapphire crystal provide best performance in every light condition.

The solid 316 brushed stainless steel case, the screwed-in 2mm thick caseback, the 8mm diameter crown coupled with fat 5.5mm screw-in pushers, together with the high quality gaskets set provide a water resistance tested individually to 30 atm=300m=1000ft.

Timing accuracy is guaranteed by the VK64 mech-quartz movement tuned to 32,768 Hz for 3 years battery life, with 1/5 of second indication plus 60 minutes counter.  Comes on a black heavy-duty Unimatic nylon nato strap with a stainless steel brushed hardware signed Unimatic.

The caseback features the Unimatic world timer engraving and the individual progressive number. The watch is covered by a 24 months worldwide warranty and is part of a unique edition of 600 pieces.
