Description

In 1956 Ervin Piquerez SA designed the “Super Compressor” watch case that, with its unique sealing method, set it apart from other dive watches. It’s also said that Aquastar circa 1960 introduced watches with rotatable chapter rings to mark elapsed time. Twin-crown dive watches with rotatable chapter rings were the rage in the 1960s.

The Chrononaut collection seeks to revive the design of twin-crown watches while using modern materials and manufacturing techniques. Even as we maintain the signature styling cues of Gruppo Gamma, watch aficionados would immediately recognize the subtle tribute we pay to the classic watches of times past.

The name ‘Chrononaut’ came about because the watch keeps track of two time zones. The rotatable chapter ring marks a second time zone and is useful for overseas travelers, workers collaborating with team members from other countries, as well as folks with loved ones residing in different time zones. With intensely bright luminescent markers the Chrononaut ensures readability at all times.

​​While smaller and slimmer than our other collections to date, t​​he Chrononaut is no less a capable tool watch. Powering the timepiece is a Swiss automatic movement. The surgical grade stainless steel case with box-shaped sapphire crystal is engineered to a depth rating of 300 m/ 1000 ft. Two screw-down crowns – one for winding and timesetting, and the other to turn the dial ring – make this timepiece stand out from the rest.

The first Chrononaut model is the Diver’s Watches LE, a limited edition of 100 pieces and a tribute to the Super Compressor dive watch. It’s a collaboration with Diver’s Watches, the largest Facebook community dedicated to the dive watch genre and the timepieces were sold out in 22 hours.
