Grand Seiko’s SBGA463 is part of the Sport Collection. This sport watch is housed in a robust 44.2mm titanium case that is 50mm lug to lug and 14mm thick, with a sapphire crystal (with inner anti-reflective coating) and a screw down crown providing 200m of water resistance. Inside it has the Spring Drive 9R65 Caliber (assembled and adjusted by hand at the Shinshu Watch Studio) that 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 72 hours of power reserve, is anti-magnetic, and secured behind a screw-in titanium caseback.

Grand Seiko is known for intricate dials and incredible casework utilizing Zaratsu polishing to create a mirror finish. The gloss black dial and broad hands are a model of readability and compliant with ISO standard 6425:2018 with its legibility enhanced by the inclusion of Lumibrite markers at all twelve indices. The titanium used is Grand Seiko’s special Hi-Intensity Titanium, providing scratch and corrosion resistance at a weight 30% lighter than stainless steel. The SBGA463 also features a uni-directional diving bezel, and a folding pushbutton clasp on its 5-link titanium bracelet, with secure lock and a solid, sliding adjuster, giving the wearer flexibility both in varied wearing conditions and for wearing over a wetsuit.
