Founded in 1962 in Geneva/Switzerland, Aquastar has since set  milestones in the evolutio\n of the dive watch


The 2020 Aquastar Deepstar is a faithful recreation of one of the most influential dive watches of the 60s. The unique and uncluttered mono sub counter dial, combined with the small running indicator, and the patented multiple dive decompression bezel table make the Deepstar an unmatched diver-oriented tool with an instantly recognizable design.

The 2020 Deepstar retains all proportions of the original Deepstar from the 60s while relying on high end Swiss Manufacture automatic Chronograph movement instead and the manual wind Valjoux 23. This gives the new Deepstar the practicality and versatility you expect from a modern Chronograph.

A Legend of the Deep Resurfaces

The 1960s: divers were going deeper and staying down longer, mapping the ocean, discovering new worlds, and exploring the limits of human endurance and tolerance for pressure. But stay too deep too long and a diver can either run out of air or get the bends. Enter Aquastar, a watch brand founded in 1962 with the sole aim of designing and building watches and instruments for aquatic use. Aquastar’s early watches were worn by navy divers, shipwreck hunters, champion freedivers and undersea explorers. But it was the Deepstar that really broke new ground when it appeared in 1965.
