Grand Seiko SBGH289

The Grand Seiko SBGH289 is praised for its legible blue dial, strong Lumibrite, and the accurate Hi-Beat Caliber 9S85 movement. Reviewers note its bright initial lume glow, though its longevity is questioned compared to other models. The watch features Grand Seiko's Super-Hard Coating for scratch resistance and retails for €7,200. Overall, reviewers highlight the SBGH289's appealing aesthetics and robust movement as key strengths.

From video reviewers

Excellent finishing and smooth bezel action are notable features of the Grand Seiko SBGH289. A weakness of the watch is the relatively low lume brightness. Reviewers disagree on the watch's ideal lug width, with some considering 22mm a limitation for users who prefer a more standard 20mm or 21mm strap width, while others do not mention this as a concern.
