Grand Seiko Heritage 'Spring' Shunbun SBGA413

This is a modern re-interpretation of the celebrated 62GS from 1967. The 62GS was not only Grand Seiko’s first watch with an automatic movement, it was also, along with the 44GS released the same year, the watch that first expressed the design grammar, the Grand Seiko Style, that still shapes all Grand Seiko designs today. Like its predecessor, this modern re-interpretation has the characteristic sharp edges and perfect distortion-free surfaces that only Zaratsu polishing can create and a wide dial opening which was achieved thanks to a bezel-free construction.

To look closely at the dial is to be transported to Hana-Ikada, the much-loved scene at the moment soon after the spring equinox, Shunbun when cherry blossom petals scattered by the wind cover the surface of a river. The textured dial and its pale pink color capture the magic of this treasured moment in the Japanese calendar and not only express the beauty of Sakura but hint at the exquisite pleasure to be derived from a profound understanding of the ephemeral nature of time.

The watch is powered by Spring Drive caliber 9R65, which is hand assembled by the skilled craftsmen and women of the Shinshu Watch Studio.

Grand Seiko emerged in 1960 as a high-end watch line from Seiko, aiming to challenge Swiss dominance in luxury watchmaking. The brand quickly established itself with Japan's first chronometer-grade watch and later gained renown for its innovative Spring Drive technology, which combines the best of automatic and quartz movements. In 2017, Grand Seiko became an independent entity, solidifying its position in the luxury watch market.

The brand's design philosophy, known as the "Grammar of Design," was established in 1967 with the Grand Seiko 44GS. This aesthetic approach emphasizes legibility, refined appearances, and distinctive features like multi-faceted markers and hands, a half-recessed crown, and the meticulous Zaratsu polishing technique. Grand Seiko continues to push boundaries in watchmaking, as evidenced by recent innovations like the "Kodo Constant-Force Tourbillon," while maintaining its commitment to precision engineering and unique design language.
