Reviews

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

CWC SBS Divers Issue Quartz Mk.2 Day/Date

The CWC SBS Divers Issue Quartz Watch Mk.2 Day/Date is widely praised for its exceptional legibility, particularly its dial design and thickly applied Super-LumiNova which owners report remains readable all night. Its robust, toolish 41mm Monnin-style case, often noted at a comfortable 11mm or 12mm thickness, features a PVD coating that withstands significant abuse and military aesthetics that contribute to its wearability and history. Some owners find the £700 price steep for a quartz diver, and fixed spring bars are noted as a drawback. On balance, owners and reviewers rate the CWC SBS Divers Issue Quartz Watch Mk.2 Day/Date highly for its bullet-proof, great-looking design and exceptional legibility.

Grand Seiko SBGP015

Owners widely praise the Grand Seiko SBGP015 for its exceptional dial print, which casts sharp shadows under light, and its versatility, classiness, and substantial feel. The Grand Seiko 9F85 quartz movement is noted for excellent timekeeping, with one owner purchasing it as a grab-and-go option. The watch is 40mm with 200m water resistance. Overall, owners rate the Grand Seiko SBGP015 highly for its sharp dial print and reliable quartz movement.

From video reviewers

The high accuracy of the Caliber 9F85 quartz movement is a significant strength. Reviewers noted the movement's ±10 seconds per year accuracy. The limited 100-meter water resistance was cited as a potential drawback.
