This may be the rarest Diver Watch ever produced and this example is the best in the world and may be the only one for sale. In 20 years of collecting I have only seen 4 for sale including this one and I owned 100% original and in mint condition. I bought this from the original owner who bought it in geneva in 1960. Condition is spectacular for a Watch more than 60 years Old. It has been in a safe for nearly 40 and thought to be lost.
