Reference 1675 was introduced in 1960 as the successor of the reference 6542. Instead of a bakelite bezel, the model was fitted with a metal insert which was much more durable than its predecessor.

The present watch is distinguished by its excellent state of preservation and presence of all its original documents. Originally sold at the U.S. Navy Exchange in Yokohama, this timepiece is accompanied by its hangtag, invoice dated 19 August, 1967, guarantee, chronometer paper February 22, 1967, product literature, wallet and presentation box. It is even accompanied by a black and white photo of the U.S. Navy Exchange in Yokohama. This is very remarkable, considering that this watch was produced over 50 years ago.

Furthermore, its state of preservation is particularly noteworthy. The case is preserved in excellent condition and the bevels are still present. There are sharp finishes to the top of the lugs, and all proportions are robust and full. The black lacquer dial, which is correct for the serial number, is incredibly glossy and shiny with barely any marks. Furthermore, the luminous material has aged evenly with the hands and both display even and warm patina throughout.
