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.

Sternglas Naos Großdatum

The Sternglas Naos Großdatum is praised for its Bauhaus aesthetic and value, with one owner finding it an affordable alternative to other designs. However, some owners report it feels underwhelming and cheap, with a printed-on face, small font, and toy-like hands, and find the strap to be of poor quality. The watch features a 38mm stainless steel case, an Alabaster dial with beige LumiNova, and a Seiko TMI VJ76 quartz movement rated for -20/+20 seconds per month. On balance, owners and reviewers are divided, with the primary point of contention being the perceived quality and aesthetic execution of the Sternglas Naos Großdatum.
