[About this watch]
This is a 56GS made in 1971. The dial is white and has no major discoloration.
The internal movement is Cal. 5646A and has been overhauled by our company. The case is slightly sagging, but has been lightly polished and is in good condition. The medallion is slightly deteriorated. It is a 56GS with a large number of balls, but I think it is in good condition.
Due to the model year it is no longer waterproof.
