The 45GS series was the second, and final series to be manufactured by the Daini Seikosha company. The 4520-8000 and 4522-8000 adheres closely to the ‘grammar of design’ case design introduced in the 44GS models with the case being slightly smaller than its older sibling. There were just three calibres used for the 45GS series – the 4520A (no complication), the 4522A (with date complication), and the legendary 4580 VFA.

Overall, this piece is in great vintage condition. We believe that the case has just been polished once or twice in the past given that it retains sharp edges with a beautiful Tanaka grammar of design profile. The original silver/white dial is in clean condition with no visible blemishes or discoloration. The crystal has been replaced with a Seiko NOS crystal. The case back and gold GS medallion is in near perfect condition. The handset and crown are all original and in good condition. The movement has just been serviced by our watch maker and is currently running at -2.1 seconds / day.
