Grand Seiko’s SBGC201 is part of the Sport Collection and housed in a 43.5mm stainless steel case with 18K yellow gold bezel, crown, and chronograph pushers. It is 51.2mm lug to lug, with a sapphire crystal (with inner anti-reflective coating) and screw down crown providing 100m of water resistance. The Spring Drive 9R86 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. This movement is a horological tour de force providing a vertical clutch and column wheel chronograph with 30 minute and 12-hour counters, “Flyer GMT” capability (with a 24-hour hand and adjustability of the main hour hand in one-hour jumps, backwards or forwards), date, and an indicator showcasing 72 hours of power reserve.

Grand Seiko is known for intricate dials and incredible casework utilizing Zaratsu polishing to create a mirror finish. This watch has a stunning blue dial with gold hands for time, and gray hands for the chronograph and GMT functions. The yellow gold bezel features a dodecahedron (12-sided) shape, topped with a tachymeter scale in matching blue ceramic, and a sapphire case back to view the movement. This Grand Seiko comes on a five-link polished and satin finished bracelet with a three-fold clasp (with an 18K yellow gold GS medallion) and micro-adjust to finely adjust the fit.
