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.

Redux Zero-Hour

Owners widely praise the Redux Courg Zero Hour 39MM for its robust, utilitarian design inspired by pilot and dive tools, its lightweight Grade 5 titanium construction, and its comfortable wearability. The proprietary RDXB1 lume is noted for its bright initial glow, though it fades quickly. The Seiko NH53A or NH35 movement is generally considered reliable. However, multiple owners report a flimsy or fragile crown stem, and some describe the unidirectional bezel as having play or being able to rotate clockwise by one minute, though one owner reported a tight bezel with no play. The 39mm case size is considered good by some, while others find it small for larger wrists or note it looks large, with some desiring a 42mm option. One owner found the titanium finish looked slightly cheap and wished for a bezel insert. The dial is described by one owner as too busy for easy reading without glasses. The Redux Courg Zero Hour 39MM is available for $300, down from an original price of $507.
