The 5646-7030 (dial code 7040T) is a rare reference in the 56 Grand Seiko series which ran from 1970-1974. It has a unique sand textured almost snow like texture to the dial and is a fan favorite amongst vintage GS collectors and is highly collectible. The dial has most certainly inspired many of the textured dial that exists in today’s modern GS lineup.
This is an all original vintage Grand Seiko 5646-7030.
Overall, this piece is in near mint condition. The case has likely never been polished in the past and retains sharp edges with upper surfaces retaining its brushed finishing. The original textured white dial is in near flawless condition with no visible discoloration. The crystal has been replaced with a 56GS NOS crystal. The handset and crown are all original and in excellent condition as is with the daydate wheel which has a lovely kanji day wheel. The movement has just been serviced by our watchmaker and is running at -8.8 seconds / day. The caseback and gold medallion is original and in good condition with some blemishes on the medallion due to aging.
