The Grand Seiko SBGH311 celebrates 25 years of achievements and challenges met, since the introduction of the very first 9S mechanical caliber in 1998.

The 37mm wide case, reminiscent the company's very first model, takes this opportunity to welcome a high frequency movement for the very first time : Hi-Beat 36000 9S85 caliber.

This discreet yet highly reliable timepiece delivers a 55 hours power reserve and specially adorns a stunning patterned dial, inspired by the sea of clouds one can witness at daybreak near the brand's Shizukuishi Watch Studio.
