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 Type 39MM for its robust, no-nonsense design and good overall quality, with a reliable Seiko NH53A movement keeping time well. The titanium case and crystal have shown scratch resistance, and the bezel action is described as tight by some. Reviewers note the proprietary RDXB1 or blue lume glows brilliantly, though briefly. Some owners flag the crown stem as flimsy and the unidirectional bezel as having some play. Overall, owners rate the Redux Courg Type 39MM highly for its functional tool-watch design and durable titanium construction.
