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 SBGR321

Grand Seiko SBGR321 owners and reviewers widely praise its attractive design, compelling dimensions, and robust movement. The watch features sharp case lines with contrasting brushing and polishing, a 40mm steel case that provides presence without bulk, and 100m water resistance. Its sunburst blue dial, inspired by the dawn sky over Mount Iwate, showcases Grand Seiko's signature finishing on applied markers and hands, with a red-tipped seconds hand. The 9S65 automatic movement is noted for its precision, running within specifications, with one source reporting a +5 to -3 seconds a day rate and a 3-day power reserve. A blue rotor with a crimson rim, also inspired by Mount Iwate, is visible through the display caseback. On balance, owners and reviewers rate the Grand Seiko SBGR321 highly for its exceptional finishing and compelling blue dial design at its price point.

CWC SBS 1987 Aged Special

Owners widely praise the CWC SBS 1987 Aged Special for its rugged build and military heritage, with some finding its quality comparable to higher-end watches. A reviewer notes the 41mm PVD-coated watch features a bright SuperLuminova dial. One owner reports a bit of play in the 60-click bezel, present from new, alongside minor wear on the PVD coating and bezel insert. On balance, owners rate the CWC SBS 1987 Aged Special highly for its rugged build and military heritage, despite some questioning its value at £700.
