In the 1940s, frogmen performing underwater operations typically wore on their wrists three types of instruments - compass, wristwatch and depth gauge.

Much has been said and done about the watch but in 2019, Gruppo Gamma took inspiration from the depth gauge instead. Using a jumping hour complication, the Nexus has risen to become an iconic tool watch.

The Nexus concept and renders were publicly unveiled in March 2019, and the prototypes were showcased in September 2019.
