I actually have three of these 1960s divers watches. This watch, the first, was purchased in 2003 but lacking the stainless steel bezel. Later I was fortunate to be able to purchase a similar watch, suitable only for spares, and placed the bezel on this watch to make it complete. This watch is different from the second and third watches in that it has a triangle at the 12 o'clock position, the other two only have a luminous dot and the movements are different. The watch in the photographs was fully serviced by Le Cheminant Watch Co in August 2003.
