Grand Seiko’s SBGJ255 is a Limited Edition of 1200 and part of Heritage Collection. It is housed in a 40mm titanium case that is 46.2mm lug to lug, with a curved sapphire crystal and screw down crown that provide 100m of water resistance. This watch case, known as the 44GS, is based on Seiko’s grammar of design, focused on flat, geometrically perfect surfaces polished to best reflect light. This watch is powered by Grand Seiko’s Automatic Caliber 9S86, providing 55 hours of power reserve. This caliber is a high beat GMT movement, beating at 10 beats per second (or 36,000 per hour) with precision of +5 / -3 seconds per day, and is visible behind a sapphire case back, with a custom gold colored rotor. 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.

This watch case, while having the comfort and low weight of titanium, is polished using the Grand Seiko Zaratsu technique and has a sheen that will deceive the eye into thinking it is stainless steel. 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 appears to be a simple white finish, but has subtle graining, with a blue GS logo, GMT text and rehaut marking, and a heat blued GMT hand add harmonious color. Lumibrite (rarely seen on a 44GS case) adds further interest to the dial and hands. This Grand Seiko comes on a five-link polished and satin finished bracelet with a three-fold clasp and two half links to finely adjust the fit.
