Grand Seiko Evolution 9 Spring Drive – SBGC251

Grand Seiko’s SBGC251 is part of the Evolution 9 Collection and is housed in a robust 45.3mm titanium case that is 52.6mm lug to lug, with a sapphire crystal, bi-directional GMT bezel, 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. The case of this watch uses the Evolution 9 Style, which expresses Grand Seiko’s new design language and will be an important part of their signature in years to come. With its complex faceted case, highly legible hands, and prominent markers, it provides ergonomic proportions for its distortion-free finish. 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 dial is a deep black, with Lumibrite on the hands, indices, and matching black, sapphire topped, GMT bezel, providing great legibility, and a sapphire case back to view the movement. This Grand Seiko comes on a five-link satin finished bracelet with a three-fold clasp and micro-adjust to finely adjust the fit.
