About Grand Seiko

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.
