What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Bremont Supermarine 300M

The Bremont Supermarine 300M is praised for its comfortable 40mm and 42mm case sizes, with owners noting the 42mm wears well on smaller wrists due to its lug design. One owner highlights the 13mm thinness of the 40mm case, considered compact for a 300m diver. The watch is priced at $1375. On balance, owners and reviewers appreciate the Bremont Supermarine 300M for its wearability and compact dimensions, especially for a dive watch.

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.
