Famous and much sought after diving chronograph, stainless steel case, 1960’s, first chronograph water resistant up to 100 m, it was a toolwatch used by the team of the french scientist and explorer Commandant Cousteau on board of his Calypso.
The watch is in excellent conditions overall, with light wear marks consistent with age and use. The light brown/grey dial presents an astonishing silver dust patina and the indexes and hands have a matching patina. There is a small dent on the case at 12 and a tiny line on the second dial under 30, both “defects” not so visible at first sight. The writings Aquastar Genève DEEPSTAR 10 ATM Swiss Made T are very legible. All the inscriptions on the bezel are also in great conditions.
