The SBGA211 Snowflake features Seiko's Spring Drive caliber 9R65, a hybrid movement combining mechanical mainspring power with electronic quartz precision, offering 72-hour power reserve and ±1 second per day accuracy in a titanium case. The watch showcases Grand Seiko's distinctive finishing techniques, including uniquely executed surface decoration on the rotor and bridges created with a diamond cutter rather than traditional abrasive methods.
