Grand Seiko Heritage Quartz GMT SBGN027

The stainless-steel case of both references measures 39mm in diameter, 12.3mm in thickness, and 19mm in lug width. The case is rated to 100 meters, features a screw-down crown at the four o’clock position, and has a dual-curve sapphire crystal surrounded by a fixed stainless-steel bezel with a 24-hour scale. The case has a good sense of balance and proportion, resulting in a watch that feels just right on the wrist. Zaratsu-polished surfaces contrast against the hairline-finished ones, highlighting the elegant geometry of Grand Seiko’s distinct design philosophy.
