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.

Spinnaker Cahill Automatic

Owners widely praise the Spinnaker Cahill Automatic for its attractive vintage-inspired design, comfortable wearability on smaller wrists, and good timekeeping, with one owner specifically noting the large "maxi" indices and NATO strap as highlights. However, some find the lume application uneven and note the use of a mineral crystal. A significant concern raised by one owner is a report of internal component failures and a perceived lack of quality control within the brand. On balance, the Spinnaker Cahill Automatic is well-regarded by owners for its style and value, particularly at specific price points, despite some noted manufacturing inconsistencies.
