1960’s stainless steel 100m diving chronograph, famous for being one of Commandant Cousteau’s team most used watch.
This serial has one of the last dial versions, with Aquastar Genève and Swiss made T only writings, (without Deepstar 10 atm) giving a particular “zen”/distraction free aspect. The opposite being the Duward Rally dial that you can also see here, for comparison.
The watch is really in Incredible conditions, near mint. The sun dark blue-gray dial is magnificient. Words are probably useless, look at the pictures. There are signs of ageing but really tiny. The matching patina on hands and plots is gorgeous too. Case is unpolished. The unique rotating bezel, with all its scales (decompression time among others) is rare in these conditions, still with its black colour.
There is a date (12-11-75) engraved in the backcase which shows signs of use.
The watch has the original Swiss Tropic strap and Aquastar buckle.
