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 SPEEDTIMER Mechanical Chronograph Limited Edition

The Seiko Prospex SPEEDTIMER SPEEDTIMER Mechanical Chronograph Limited Edition is praised for its well-executed heritage inspiration, clean dial, and balanced design, with its in-house caliber 8R48 noted as a solid movement. Owners appreciate the Zaratsu polishing and the column wheel and vertical clutch on the 8R48 movement, considering it good value. Some find the date wheel deep-set and the bracelet lacking micro-adjustments. The 42.5mm x 15.1mm case size may be large for some wrists. On balance, owners and reviewers rate the Seiko Prospex SPEEDTIMER SPEEDTIMER Mechanical Chronograph Limited Edition highly for its heritage design and solid in-house movement.
