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.

Tissot Seastar 1000 Powermatic 80 GMT

Owners widely praise the Tissot Seastar 1000 Powermatic 80 GMT for its excellent build quality, smooth winding feel, and the reliable Powermatic 80 movement providing an 80-hour power reserve. Reviewers highlight its remarkable value under $700, comfortable wearability, and appealing case/dial ratio. Some owners note the bezel's functionality for tracking a second time zone and the need to adjust the hour hand for date setting, a characteristic of its "True" GMT function. The rubber strap is considered comparable to those found on significantly more expensive watches. However, concerns exist regarding the movement's serviceability due to potential plastic components and reliance on Swatch Group service centers. Some find the bezel font and dial spacing unappealing, while others question the mineral glass bezel insert as a cost-cutting measure compared to ceramic. Accuracy is generally reported as good, though not COSC certified, and lume intensity is described as average by one owner.
