Hello Watchexchange, Up for sale is this Seiko Grand Quartz (Ref: 4843-8040) from November 1975. The Grand Quartz was the continuation of the Grand Seiko line, but then in quartz. The Grand Seiko Guy did a very good piece on these (https://thegrandseikoguy.substack.com/p/a-history-of-grand-seiko-1975-to-1988) These GQ were already thermocompensated, which is why they were very accurate (+/- 5 seconds per month). Cosmetically, this GQ is in good condition. There are hairline scratches throughout the case. The original hardlex crystal also has some scratches. The GQ still keeps time well: approx 8 seconds slow per 24 hours, measured by laying flat for 24 hours. The watch currently has a used Seiko leather strap, which is potentially ready for replacement. Please look at the pictures carefully and let me know in case of questions and/or remarks.
