Genesis, Mk I - III


The Genesis collection marked the beginning of our brand. It was available from 2013 to 2016, through its Mk I (2013/14), Mk II (2014/15) and Mk III (2016) iterations. The collection was born of our desire to recreate the legendary tool watches issued to Italian frogmen in the 1950s. While case and dial design was based on the Rolex Reference 6152, case diameter was reduced to 44mm from the original 47mm, and case shape was revised for better fit. There were two dial designs, Arabic 12-3-6-9 and "California", and in various colors. Some dials had small seconds display. One had dot minute markers, a design that would later become Gruppo Gamma's signature.

About the Brand


  • Vintage-Inspired


    Founded in 2013 as an independent brand, Gruppo Gamma has been creating vintage-inspired tool watches that are easy to read, fuss-free to operate and good enough for daily adventures.

    Our brand name was inspired by the Italian frogmen unit of the same code name, the first modern naval diver unit put to action in 1940. The top secret elite force was called "Gruppo Gamma" which was said to have originated from the Pirelli rubber skinsuit, called "muta gamma", used by the divers. For underwater operations the divers were issued timekeeping instruments repurposed from pocket watches, worn on the wrist using leather straps.

    Gruppo Gamma has, in a short span of time, grown into a brand that's appreciated by collectors and enthusiasts.​ Within months of our brand's creation our customers created an online owners' club. Today, this community comprises customers, supporters and dealers from all over the world.
