When Gruppo Gamma was set up in 2013, our primary motive was to revive the spirit of older tool watches - most notably those built for combat divers from days gone by.


In 2019, Gruppo Gamma is delighted to introduce the Nexus collection. Like its forebears the timepiece is inspired by vintage diving instruments, but with a twist.


Back in the day, 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 now we have taken inspiration from the depth gauge instead.


The Nexus uses a special wandering hour complication. First seen in the market some years ago, Gruppo Gamma now adopted it to give the Nexus a distinct character that is reminiscent of the vintage diving instrument.
