Seiko H357 5040
The Seiko H357 5040 was used by Bond in the 1981 movie For Your Eyes Only. In the movie Bond receives a message on the digital display.
This watch is, like all the Seiko's used in Bond movies, quite rare. Beware of sellers on eBay offering similar Seiko models, claiming it to be the Bond watch, but there is only one correct model Seiko H357 5040, and that is the one pictured here.
