What people say

Owners + reviewers, side by side

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

CWC SBS Divers Issue Quartz Watch 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 that remains readable all night. Owners appreciate its robust, toolish, bombproof design and comfortable wearability, with one noting its 11mm thickness and smaller wear size. The PVD finish withstands significant abuse. The Ronda movement is considered to have consistent second-hand movement. Some find its £700 price steep, especially compared to less expensive quartz divers, and fixed spring bars are noted as a drawback. Customer service is also flagged as potentially lacking by some. Overall, owners and reviewers rate the CWC SBS Divers Issue Quartz Watch Mk.2 Day/Date highly for its military aesthetics, legibility, and robust, comfortable tool-watch build.

Seiko Prospex SPEEDTIMER Mechanical Chronograph

The Seiko Prospex SPEEDTIMER Mechanical Chronograph is praised for its handsome, heritage-inspired design with a clean, balanced dial and an external tachymeter bezel. Reviewers highlight the upgraded case and bracelet, noting improved comfort and good value for a well-designed chronograph with an in-house movement. The caliber 8R48 movement features a vertical clutch and column wheel with MEMS technology for durability and precision. Points to consider include the 4:30 date window and a 14.6mm thickness, while the 45-hour power reserve is noted as an area for potential improvement. On balance, reviewers find the Seiko Prospex SPEEDTIMER Mechanical Chronograph to be a solid offering with good value, particularly for its design and in-house movement.
