Seiko Cronos - Pre DIVER - ' water 50 proof' - j13046
A stunning example of the technology that Seiko was hunting for in the late 50’s. The watch housing a triple locking caseback and double screwed down balance bridge. All to be able to withstand the high pressure a watch needed to withstand in rough conditions.
The watch is serviced, runs on a hand wound seiko movement and is sold with a perpetualwatchlover strap of your choice.
