[About this watch]
This is a 56GS manufactured in 1971. The 56GS is one of the more common Grand Seiko models, but this one is rare with its dark blue dial. There is some discoloration near the 10 o'clock position, but overall it is in good condition.
The internal movement is Cal.5646A and has been overhauled by our company. The case has been lightly polished to preserve the GS's unique streamlined case lines. There are no scratches on the glass.
It has become non-waterproof due to age.
