This model is difficult to restore to perfect condition, so we hope that those who understand vintage watches will purchase it. The movement is very well made, so it can still be used for a long time. ■ Comments Recommended for those looking for a SEIKO quartz watch or a retro diver's watch. Get a well-maintained Japanese retro wristwatch and enjoy it for casual everyday use. This is a popular model that served as the design prototype for the mechanical diver, SKX series (Black Boy, now discontinued). It features a matte black dial and mirror indexes, familiar from the Sumo.
