Here is a wonderful, all original Grand Seiko GS56 Hi-Beat from 1970. The silver sunburst dial is in good condition, with steel Seiko and GS logos and steel strip hour markers, double at 12 o’clock. There is a discolored spot just right of the 12 o’clock hour marker and a tiny spot close to the 7 o’clock hour marker and there is some wear around the edge of the dial, most notable at around 3, 6 and 8 o’clock. 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 the date and the weekday in English and Kanji, both of which can be quick-set with the crown pulled out to the middle position. This should only be done with the hour hand at the bottom half of the dial.

The stainless steel bezel is in fine condition with some overall wear, perhaps most prominently at around 12 o’clock. The cushion shaped stainless steel case with integrated lugs and the original GS crown has a brushed finish and is in fine condition with a few marks on the face towards the lugs as well as a small scuff at around 12 o’clock close to the bezel. The stainless steel case back has a slightly worn gold GS medallion and is in fine condition with some scratches and marks throughout.

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 May 2024 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.
