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 complication versions. In all there were 35 different models in the 56GS series.

This is an all original vintage Grand Seiko 5646-7011. Overall, this piece is in excellent condition. The case has been polished in the past but retains sharp edges with a beautiful Tanaka grammar of design profile. The original matte white dial is in excellent condition with no major blemishes in the dial. The handset and crown are all original and in great condition as is the daydate function which has a lovely Japanese kanji day wheel. The gold medallion on the caseback is original and has minor chipping along its edges. The movement was serviced in December 2022 and is currently running at -5.6 seconds/day.
