This stainless steel Seiko, model A128-5010, has all the functions working and is fitted with the original good length bracelet.


We can date this to being made in October 1977 from the serial number on the watch back.


​Used but not abused.  The glass has a few marks from general wear and tear, but the case and original bracelet have not dents or dinks.  The bracelet is a good length too and has been cleaned in our ultrasonic bath.  The end links to the bracelet do have some slack in them, but they do not seem distorted.  All functions work including the light, but don’t expect this to be dazzling as they were never that good when new!  Quite a chunky watch that would not have been cheap back in 1977.  The full instructions for this model can be downloaded here.

Please see the HD video below for more details.


Approximately 40.6 mm wide including the pushers, 15.8 mm thick. The bracelet will fit wrists up to 190 mm.
