From Gruppo Gamma

The Genesis has returned, after a hiatus of 10 years. It retains the original 44mm case of surgical-grade 316L stainless steel, but is subtly redesigned. The black classic dial in sandwich construction, with hour indices, dot minute markers and a cleverly designed date window, shines like a torch in the dark, thanks to the generous application of Swiss Super-LumiNova of the highest grade. Inspired by a rare military prototype from the 1950s, the dial design has since become Gruppo Gamma's signature. The timepiece is powered by the venerable Sellita SW200-1 Swiss automatic movement, and is water resistant to 200m/ 660ft.
