Cool La Spirotechnique divers depth gauge made in France. It is model Z30 from the 1970’s. Could be used for depths up to 160 meter which was good for professional divers. These were also used for military purposes but I do not think the number (twice) on the back is military. It has a beautiful orange and white centre hand, same colors as used on the dial (mint condition). It is also on the original rubber strap that would fit over a very thick divers suit. The thick chromium case measures 5, 5 cm or 2 1/8 inches in diameter. Very thick original glass with a few small scratches only. Clear signs of use and age on the case, showing it’s tool heritage Very cool item that breaths vintage all the way down! Do read the blog post on collecting diver depth gauges and other equipment.
Vintage watch guarantee and ideas on use:
All vintage watches I sell are tested and working correct. When they needed service or adjustment this has been done by a professional watchmaker. I do not keep paperwork on every separate watch. I cannot give a long guarantee on vintage watches since it depends on how careful they are handled. Sometimes rough shipment can hurt them, no matter how well I package them. I will always take them back when there are problems upon receiving or in the first weeks of use. Please treat your vintage watch as a precious old timer car. Do not go out in the rain, play sports with them or take them on long holidays. Do buy a good watch box to keep them in and change your strap in time. Wear them for a few days at a time and change them out. Do not set the date when the hands are within a few hours before or after 12 o’ clock. Never use force, sent me an email if you are not sure on how to work your vintage watch.
