It played a crucial role in popularizing automatic movements in Japan. The 6206 caliber found in this model is part of the legendary 62-series family, which would eventually serve as the base for the first automatic Grand Seiko, the 62GS. Owning this watch is owning a direct ancestor to some of the most prestigious watches ever produced in Japan. / Second Vintage SKU: SEI-SJX-0004
