Gruppo Gamma Nexus

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

Modelled after vintage depth gauges used by frogmen in underwater operations.
Clever use of jumping hours, resulting in one of the most iconic timepieces in its genre.
Go back in time with aged steel, or Damascus steel and stainless steel options.

Our view
An incredible watch – the Nexus has a design based on the vintage hand gauges used during the 40s from last century. This is the most unconventional watch in Gruppo Gamma line up and we have to say it really is a conversation piece. Many watch collectors compare it with Swiss creations that are 10-30x more expensive and are literally shocked when they realise there’s a small company like Gruppo Gamma behind and you don’t have to pay so much to get it.
