The 45GS series was the second, and final, Grand Seiko series to be manufactured by Daini Seikosha Kameido (Tokyo) Factory. There were four case variations introduced in the 45GS series and this particular example features the rare 7000 case variation. The 7000 case series features a highly angular design and is nicknamed the "turtle shell" by Japanese collectors. This 7000 case series were available in both steel and cap gold variants, with the steel versions being available with two different dial finishes – white linen textured, and a dark blue matte. The production period was short for the 7000 case series when compared to the other three case series in the 45GS - hence the rarirty of this variation.
Overall, this all original 45GS is in great vintage condition. The case has some nicks/surface scratches but appears to have been unpolished. The original and beautiful dark blue matte dial is in very clean condition with no blemishes. The handset and crown are all original and has honest ageing but otherwise in good condition. The movement has been serviced in August, 2019 and has been checked by our watchmaker and is currently running at an excellent +2.2 sec/day. The caseback and gold medallion is original and is in near perfect condition.
