SEIKO Grand Seiko Spring Drive
We have received a Grand Seiko Spring Drive PWR model equipped with SEIKO's unique hybrid movement, "Spring Drive." This is SEIKO's proprietary drive system that incorporates the best of both mechanical and quartz watches. It uses a mainspring, as found in mechanical watches, as its power source, but its accuracy is controlled by a quartz crystal oscillator, the control system of quartz watches, through precise signals.The black dial features a date display at the 3 o'clock position and a power reserve indicator at the 7 o'clock position.The exterior has been polished and the movement has been inspected by our affiliated repair workshop. There are scuffs on the bezel and lugs.
Maintenance:Polishing and mechanical inspection
Bracelet inner circumference:Approximately 20cm
