Grand Seiko 56GS 5646-7010





The 56GS series was introduced in 1970 and offered a wide variety of models with 35 in total. This reference was also the first to introduce an ultra-thin automatic caliber, at just 4.5mm. Following the Grammar of Design rules, the -7010 and -7011 cases come with sharp edges and brushed finish to the surfaces between the lugs and are the most common vintage Grand Seiko that you can find on the market.


This example we have to offer is the Grand Seiko 56GS Ref.5646-7010, white dial, in stainless steel. Although a common model, this particular one is unused and retains its original factory finishes with the blue protective film still intact.
