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 LX line

Owners widely report the Seiko Prospex LX line's finishing is a step up from other models, with a case that sits well on the wrist, and some praise the green sunburst dial with blue anti-reflective sapphire crystal as phenomenal. However, owners note the high MSRP limited sales, with some desiring smaller cases and a reduced price, and others experienced quality control issues such as detached second hands and peeling DLC coating, leading to concerns about fragility. On balance, owners feel the Seiko Prospex LX line was discontinued due to pricing that alienated its target market, despite its attractive dial.
