Grand Seiko's story began in 1960, a time when Swiss watchmaking reigned supreme. Undeterred, a group of dedicated Seiko engineers and watchmakers set out to create timepieces that would rival the best in the world. Their pursuit of precision, legibility, and beauty led to the birth of Grand Seiko, a brand that would come to define Japanese watchmaking excellence.



Grand Seiko's early years were marked by a relentless pursuit of accuracy. The brand's first watch, the 3180, was a mechanical marvel that set new standards for precision. Over the years, Grand Seiko continued to innovate, introducing groundbreaking technologies such as the Hi-Beat movement and the quartz-powered 9F caliber.



In 1999, Grand Seiko unveiled a movement that would revolutionize the watchmaking world: Spring Drive. This unique caliber combined the best of mechanical and electronic watchmaking, offering quartz-like accuracy without the need for a battery. The Spring Drive's glide wheel, a marvel of micro-engineering, ensured a smooth, continuous sweep of the seconds hand, a visual testament to the movement's precision.



The first Grand Seiko 9R Spring Drive watch appeared in 2004, after years of intensive development. The Caliber 9R, with its 72-hour power reserve and automatic winding mechanism, set a new benchmark for Spring Drive technology. Over the years, the 9R caliber has evolved, giving birth to a family of movements that power some of Grand Seiko's most iconic timepieces.
