Grand Seiko Heritage Spring drive Ref. SBGA413G

• Description

  Grand Seiko Heritage Spring Drive

  When sakura flowers fall into the water, they swirl and float. The pink flowers dance on the water and the Japanese call them rafts of flowers, hanaikada. The pink dial of this model captures the spirit of the fleeting sakura season.

  Case design: the iconic modern reinterpretation of the 62GS

  Launched in 1967, the 62GS was Grand Seiko's first automatic movement. This timepiece gained popularity for its striking design featuring a multi-sided mirror case and a wide dial aperture, achieved by Seiko's signature Zaratsu bezel-less construction and polishing technique. Pure, refined and noble, the 62GS is a precious classic.

  Movement: caliber 9R65 that Grand Seiko assembles in its Shinshu Watch Studio, located in Nagano Prefecture. This sophisticated movement combines modern technology with the skilled hands of master craftsmen for its fine adjustments and high precision. The Spring Drive movement further reflects the smooth flow of time with each revolution.
