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.

Tudor Black Bay Ceramic

The Tudor Black Bay Ceramic's matte ceramic case and bracelet offer a stealthy, scratch-proof aesthetic that shifts from anthracite to gray in light. Reviewers note its comfortable wearability, with one highlighting improved comfort over steel versions, and praise the METAS-certified MT5602-U movement. However, the sandblasted finishing is described as lacking contrast, and the bracelet's butterfly clasp omits on-the-fly adjustment. The PVD-treated steel bezel ring is also flagged as a potential wear-and-tear vulnerability. On balance, reviewers find the Tudor Black Bay Ceramic appealing for its unique ceramic construction and durable, stealthy finish, despite some functional limitations.
