Grand Seiko Heritage Collection SBGH299G
With its screw-down crown, one-way rotating bezel and water resistant to a depth of 100 meters, this watch provides all the security and legibility that the diver requires. It also offers the precision and durability of Grand Seiko's divers' high-beat movement, Caliber 9S85.
The unique design, whose primary feature is a polished, undistorted surface, reverberates with a beautiful radial dial pattern, giving rise to an expressiveness that weaves together light and shadow in an aesthetic sense that the Japanese have appreciated since ancient times.
The movement is the Hi-Beat Caliber 9S85, which beats 10 times per second and grants more stable precision through resistance to interference and maintaining consistent accuracy.
