This slim three handed dress watch is in a rectangular case, and is in very good condition.  Model 5Y31-510A


From the serial number on the case back we can accurately date this watch to being made in September 1997.


There isn’t a lot to say here, as the was is in fantastic condition.  The glass is flawless, the dial likewise.  The dial does have an unusual brick pattern to it, which the photographs show nicely.  The Seiko 5Y31 quartz movement is working the way Seiko envisaged it would, and a new battery will be fitted prior to this being sent out.  We have fitted a new old stock Ingersoll leather strap with gold tone buckle.  The only sign of wear is a small scratch on the caseback, where a tool has slipped when a battery change happened.

This watch will be supplied with our Certificate of Authenticity.
