Grand Seiko GS56 Hi-Beat

Grand Seiko GS56 Hi-Beat

SKU: VWS-1170

Here is a wonderful and rare, all original Grand Seiko GS56 Hi-Beat from 1970. The unusual for a GS silver sparkle dial is in fine condition, with steel Seiko and GS logos and steel strip hour markers with black contrast, double at 12 o’clock. There is some discoloration and wear at around the 6 to 8 o'clock hour markers. The black fils hands are in very fine condition, with the characteristic seconds hand for this model without a center hole. When the crown is pulled out to set time, the hack stops the seconds hand for more accurate time setting. The steel framed window at 3 o’clock shows the weekday and date, both of which can be quick-set with the crown pulled out to the middle position.


The stainless steel bezel is in very fine condition, with only light overall wear. The cushion shaped stainless steel case with integrated lugs and the original GS crown has a brushed finish and is in very fine condition with a few marks towards the lugs. The stainless steel case back has a somewhat worn gold GS medallion and is in fine condition, with some scratches and marks.


The watch comes on an after market leather strap of good quality.


Inside the watch, Seiko’s high grade 5646A movement beats strongly and accurately to within about +-12 seconds per day. The watch was fully serviced in August 2020 and comes with a 12 month warranty on its proper mechanical functioning.


The Grand Seiko was made to show the world the prowess of Japanese watchmaking and proved their right when outperforming every other mechanical watch in observatory tests. They remain some of the most iconic and collectible vintage watches with an outstanding design and engineering quality. This 56GS Hi-Beat is a great example of that and it is a fine watch for any occasion.



Our watches are delivered in a luxury wooden watch box, fully serviced with a 12 month warranty that covers the mechanical functioning of the watch under normal use. We offer 14 days full return rights and are very proud of our reputation for outstanding customer satisfaction.
