Grand Seiko SBGC013 Chronograph
Limited Edition of 400 Pieces
Since its birth in 1960, every Grand Seiko watch has shared the same commitment to the pure essentials of watchmaking: precision, durability, legibility and beauty. This 55th anniversary Limited Edition features enhancements in each of these essential characteristics of Grand Seiko.
Precision: A specially tuned version of Spring Drive caliber 9R96
This Limited Edition houses the unique Spring Drive movement, specially tuned for enhanced accuracy. The crystal oscillators are selected individually with time and care, realizing an accuracy of +/- 0.5 seconds a day (+/- 10 seconds per month). A lion emblem in 18K yellow gold graces the oscillating weight to symbolize the enhanced accuracy.
Durability: A ceramic bezel, seven times harder than steel
This is the first ever Grand Seiko watch to use a ceramic bezel. The deep black ceramic on the bezel gives the watch a crisp and refined appearance. Ceramic is seven times harder* and 25% lighter than stainless steel, and scratch resistant. Its surface is specially polished to the highest possible level to create a long-lasting and super-flat mirror finish. *on the Vickers scale
