Inspired by the 1967 Grand Seiko classic known as the 62GS, Reference STGK011 features a bezel-free case construction with a dial surrounded by diamonds. The dial's deep purple color is known as Koki-murasaki, and it's long been a symbol of status in Japanese society. There are two diagonally positioned diamonds at 12 o’clock, and the leaf shaped hour indexes, like the tapered hour and minute hands, are polished to ensure both their beauty and legibility.
The Grand Seiko automatic Caliber 9S27 perfectly balances high performance and size in a way that only a true manufacture can achieve. Despite its diminutive dimensions, the movement's specifications are outstanding, with a precision rate of +8 to -3 seconds a day and a power reserve of 50 hours. Each movement is manufactured, assembled, and adjusted by hand at Studio Shizukuishi in northern Japan and enjoys the same level of craftsmanship that goes into every other Grand Seiko mechanical watch.
