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.

Grand Seiko SBGN027

Owners widely praise the Grand Seiko SBGN027 for its exceptional Zaratsu polishing, compact 39mm size, and versatile monochrome aesthetic, noting its thin profile and suitability as a grab-and-go watch. The 9F quartz movement delivers highly accurate timekeeping, with one owner reporting +/- 10 seconds per year. However, some find the lume limited, the bracelet lacks micro-adjustments, and the GMT hand can be easily mistaken for the minute hand. One owner reported a black index on the bezel disappearing after a couple of months. On balance, owners rate the Grand Seiko SBGN027 highly for its premium finishing and accurate HAQ GMT movement in a wearable size.
