Aquastar Deepstar II on stainless steel BOR bracelet

Collection · 1962

Aquastar Deepstar.

The watch that started it all. The chronograph Frédéric Robert built for the Marine Nationale, same case, same bezel, every Swiss movement we’ve made since.

The Deepstar story

The world’s first multiple-dive no-decompression chronograph.

In 1962 the Deepstar shipped with a Valjoux 23 column-wheel chronograph and a bezel marked with the actual decompression tables of the Marine Nationale. Sixty years later, every Deepstar is built from the same archive drawings, just with a hand-wound La Joux-Perret movement in place of the Valjoux 23.
