About Grand Seiko

Founded in 1960 with the ambitious goal of creating the "ideal" watch, Grand Seiko represents the pinnacle of Japanese horological mastery. Every timepiece is a tribute to the brand’s unique philosophy, which blends high-precision engineering with a deep reverence for the natural world. Grand Seiko is renowned for its "Grammar of Design," a set of aesthetic rules established in the 1960s that prioritizes sharp, flat surfaces and mirror-polished finishes—achieved through the legendary Zaratsu polishing technique. The brand is a true manufacture, developing every component in-house, including three distinct movements: the high-beat mechanical, the ultra-precise 9F quartz, and the revolutionary Spring Drive, which features a perfectly smooth, gliding seconds hand. Inspired by the changing seasons and the landscape around their studios in Shizukuishi and Shinshu, Grand Seiko dials often feature intricate textures like the celebrated "Snowflake." At IJL, we are proud to offer Grand Seiko to collectors who appreciate a refined alternative to Swiss luxury, where incredible technical accuracy meets the quiet beauty of Japanese craftsmanship.
