Youtube: Why the Grand Seiko SBGA415 Winter is the best choice vs. the SBGA413 Spring

Taisetsu: The Deep Snow of Winter
Pine trees crusted with snow, silent under the sun of winter. It’s when the world has settled into a slumber only to awaken in the spring. This model’s dial celebrates the winter snow as it gathers and glitters against the sunlight.

Case Design: The Iconic 62GS Modern Reinterpretation
Launched in 1967, the 62GS was Grand Seiko’s first automatic movement. This timepiece gained popularity for its striking design featuring a mirrored, multi-sided case and wide dial opening, which was achieved with bezel-free construction and Seiko’s signature Zaratsu polishing technique. Pure, refined, and noble, the 62GS is a treasured classic.

Movement: 9R65 caliber 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 craftspeople for its fine adjustments and high precision. The Spring Drive movement further reflects the smooth passage of
time with every revolution.
