Grand Seiko GS45 Hi-beat 36000bph

SKU: VWS-1669

Here is a wonderful, all original Grand Seiko GS45 Hi-Beat from 1969 in a very large size. The dark navy dial is in very fine condition, with steel Seiko and GS logos and faceted steel strip hour markers, double at 12 o’clock. Upon close inspection some of the markers show some corrosion. The tapered, faceted baton hands are in very fine condition. When the crown is pulled out to set time, the hack stops the seconds hand for more accurate time setting.


The stainless steel bezel is in fine condition, with only light overall wear apart from a more noticeable nick at around 5 o’clock. The sunburst pattern angular 7000 series stainless case has integrated lugs and the original GS crown and is in fine condition with some overall wear, most notable towards the lugs. The stainless steel case back has a well preserved gold GS medallion and is in fine condition, with a few scratches and marks.


The Seiko steel bracelet is in fine overall condition with some noticeable marks at the lower first link. It shows little stretching and is big enough for moderately large wrists.


Inside the watch, Seiko’s high grade 4520A movement ticks away at the then insane frequency of 36000 beats per hour, beating strongly and accurately to within about +-8 seconds per day. The watch was fully serviced in March 2022 and comes with a 12 month warranty on its proper mechanical functioning.


A Grand Seiko is always an attractive proposition, and dark dial watches look even more alluring. With the large size and wonderful overall condition, this is a watch that will add to any vintage collection while it is also great as part of a regular rotation schedule.  



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.
