SBGA211 : Grand Seiko Spring Drive Stainless Steel / Snowflake / Bracelet


The Grand Seiko Spring Drive SBGA211 was introduced when Grand Seiko became a separate brand rather than a collection within the Seiko family in 2017. This watch is powered by caliber 9S65 and features a stainless steel case and matching bracelet. The dial is white dial features a subtle grain that earned it the nickname 'Mount Iwate'.


Grand Seiko caliber 9R65 Caliber 9R65 is a self-winding movement based on Seiko's Spring Drive technology. It is currently the most standard of the 9R Spring Drive movements, and is used in many Grand Seiko models.

Spring Drive, one of the great innovations in modern watch making history, regulates a spring-driven movement with state-of-the-art electronic technology that functions without batteries or other external power source. Its sole power source is a mainspring, which drives a series of gears. A rotor, connected to the end of these gears, generates a small electrical charge that activates an electronic circuit and quartz oscillator. Its accuracy is unprecedented for a watch wound by a mainspring. The development of the 9R Spring Drive movement was possible only because Grand Seiko is one of the few manufacturers with expertise in both mechanical and electronic watches.
