Grand Seiko Heritage 60th Anniversary Limited Edition Mechanical Hi-Beat 36000 SBGH281

The 60th anniversary celebration starts with two automatic watches that are unmistakably and quintessentially Grand Seiko. The menÕs watch pays homage to the famous 44GS from 1967 whose design was the first ever expression of the uniquely Japanese Grand Seiko Style which, ever since, has been its visual signature. It features the high beat Caliber 9S85 which delivers an accuracy of ±5 to -3 seconds a day and a 55 hour power reserve. In honor of the 60th anniversary, the Grand Seiko symbol is in gold and the seconds hand is in a vivid red, colors that, together, symbolize a sunrise and all the new energy that a new dawn brings.

Calibre 9S85:

The challenge of making a high-beat movement is one that only a few watchmakers choose to accept. With its higher oscillation rate of ten beats per second, greater accuracy is achievable, but this increased precision comes at a price because the faster rotational speed can take its toll on the power reserve and even the longevity of the whole movement. Grand Seiko's 10 beat movement meets these challenges and delivers an accuracy of ±5 to Ð3 seconds a day, a power reserve of 55 hours and the durability for which every Grand Seiko watch is renowned. Caliber 9S85 is the result of many years of development and of advances both in the design and manufacture of components and in the materials themselves.
