The Grand Seiko “Sea of Clouds” GMT Ref. SBGJ275 is a striking limited model from the Sports Collection, celebrated for its vivid dial and high-performance GMT movement. The deep blue textured dial is inspired by the breathtaking view of clouds seen from the summit of Japan’s mountains, giving the watch its poetic nickname among collectors. Powered by the Hi-Beat Caliber 9S86, the movement operates at 36,000 vibrations per hour and offers exceptional precision along with a true GMT function, allowing the wearer to track a second time zone with ease. The high-frequency movement also delivers a beautifully smooth sweep of the seconds hand, a hallmark of Grand Seiko’s mechanical expertise. The robust 44mm stainless steel case features Grand Seiko’s renowned Zaratsu polishing, producing distortion-free mirror surfaces and crisp edges. Paired with a blue-and-white GMT bezel and a solid stainless steel bracelet, the watch combines sporty functionality with refined finishing. This example is in very good condition and comes as a complete full set with original box, papers, and accessories, making it a desirable piece for collectors and enthusiasts seeking a distinctive Grand Seiko GMT.
