Ref. SBGE255
The Grand Seiko SBGE255 is a compact 40.5mm Spring Drive GMT watch from the Sport Collection, notable for its innovative 9R66 movement offering a 72-hour power reserve and ±15-second-per-month accuracy. It features a ceramic bezel, screw-down crown and caseback, and a sporty design with a blue dial and LumiBrite hands. Introduced in 2020, it redefined Grand Seiko’s GMT offerings with a smaller case size, catering to those who prefer a more wrist-friendly form factor.
