What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

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.
