The 56GS series of vintage Grand Seiko is second only to the 61GS with regards to the diversity of the watches produced. The three movements that were used in this series were the 5641A (no-date), 5645A (date) and 5646A (day-date), making this the only series with all three complications. In all, there were 35 different models in the 56GS series.

This is an all original vintage Grand Seiko 5646-8000 that comes with its original Grand Seiko bracelet XQB040. Finding a 564X series with its original GS bracelet is very difficult to find even in Japan and we are very luck to offer this fantastic vintage GS.

Overall, this piece is in great vintage condition. The case has likely been polished lightly in the past and has small scratches but retains sharp edges with the lug surface showing traces of its original brushed finishing while the side surfaces of the watch is mirror polished. The original champagne sunburst dial is in excellent condition with some blemishes throughout the dial especially around the edge of the dial. The crystal is the original 56GS crystal. It has scratches and bumps but we decided not to replace it since it gives the watch character and it is quite remarkable to see its original crystal on the watch. We can replace the crystal with a new old stock GS crystal for an additional small fee. The handset and crown are all original and is aged but is in good condition. The day and date wheel is working with the quick set function fully functional. The caseback and original gold medallion is in great condition. The case back is engraved with the Japanese writing, "永年勤続表彰記念 and 48年2月（株）工正舎鉄工所" which translates to "commemoration of life time employment at Koseisha Steel factory 1973 February". A lovely handwritten engraving from a company celebrating its treasured employee. The movement service history is unknown but has been checked by our watch maker and is currently running at an excellent +5.5 seconds per day. The watch comes with its original Grand Seiko bracelet, the reference XQB040. The bracelet is in beautiful shape with some stretch as is expected due to its age. The "S" letter on the GS logo on the clasp has fallen off. The XQB040 was the bracelet initially supplied on this Grand Seiko 5645 and 5646-8000 when they were initially released. It is shown on the 1972 Seiko catalog. The bracelet can fit up to a 17cm/6.7 inch wrist size.
