Grand Seiko Sport Collection Hi-Beat Diver Titanium

The Grand Seiko SBGH291G represents the pinnacle of Japanese dive watch engineering, combining the remarkable Hi-Beat 36000 movement with aerospace-grade titanium construction. This 43.8mm professional diver features high-intensity titanium with proprietary hard coating, delivering exceptional scratch resistance while weighing 40% less than steel—a crucial advantage during extended wear underwater or on land. The black dial showcases Grand Seiko's meticulous attention to legibility: each hand features a distinct shape to prevent confusion at depth, while generous Lumibrite coating ensures visibility in the darkest environments. The gold-colored GS logo adds a subtle luxury touch to this serious tool watch. At the heart beats the legendary Calibre 9S85, oscillating at 36,000 vibrations per hour (10 beats per second). This Hi-Beat frequency delivers the smoothest seconds hand sweep in mechanical watchmaking, creating an almost continuous glide around the dial. The 55-hour power reserve defies expectations for such a high-frequency movement, achieved through innovative MEMS technology and proprietary Spron alloys. The unidirectional bezel clicks precisely every 30 seconds rather than the standard 60, offering twice the resolution for timing critical decompression stops. Deep grooves ensure secure grip even with thick neoprene gloves, while the four-part construction facilitates servicing. ISO-certified for professional diving, this timepiece combines Japanese perfectionism with real-world functionality, making it equally suited for saturation diving or boardroom meetings where precision matters. Our offering is brand new and comes in full set of boxes and papers. Covered by our limited warranty of 1 year, starting on the date of purchase.
