Grand Seiko SBGC247 Chronograph GMT Watch
Grand Seiko launched the Caliber 9R86 movement 15 years ago. The Caliber 9R86 is still the most accurate spring drive movement available, and Grand Seiko is celebrating the 15th anniversary with the SBGC247 Chronograph GMT. The 43.5mm case features a dial inspired by the wind-blown snowdrifts that surround the Shinshu Watch Studio in central Japan during the late winter and early spring and blue for the GMT indicators. The Caliber 9R86 features a 72-hour power reserve and an accuracy of +/-15 seconds per month.
