Grand Seiko Sport GMT Spring Drive – SBGE257

Grand Seiko’s SBGE257 is part of the Sport Collection. This sport watch is housed in a 40.5mm stainless steel case (with ceramic bezel) that is 48.7mm lug to lug and 14.7mm thick, with a curved sapphire crystal (with inner anti-reflective coating) and screw down crown providing 200m of water resistance. Inside it has the Spring Drive 9R66 Caliber (assembled and adjusted by hand at the Shinshu Watch Studio) provides a smooth sweeping seconds hand with an astonishing precision of +/- 15 seconds per month, unprecedented for a watch powered by a mainspring. The beautiful movement provides GMT functionality, 72 hours of power reserve, is anti-magnetic, and secured behind a screw-in titanium case back. The “Flyer GMT” capability adds a 24-hour hand and allows you to adjust the main hour hand in one-hour jumps, backwards or forwards.

Grand Seiko is known for intricate dials and incredible casework utilizing Zaratsu polishing to create a mirror finish. The green dial and fixed ceramic bezel are inspired by the rich green of one of the 2,000 types of moss found in Japan, with a gold GMT hand providing wonderful contrast. The dial and generously sized hands filled with Lumibrite for high legibility in all light conditions. A date window and crown at 4 o’clock provide a very comfortable wrist experience, and a power reserve indicator at 8 o’clock provides status. This Grand Seiko comes on a five-link polished and satin finished stainless steel bracelet with a three-fold clasp and two half links to finely adjust the fit.
