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 5KX

Owners widely praise the Seiko 5 Sports SKX series for its strong lume and comfortable wearability, with many noting its compact feel due to a short lug-to-lug length. The NH36 movement's accuracy varies, with typical performance between +/-5 to 10 seconds per day, though some report better. A lack of screw-down crown and ISO certification are noted drawbacks for its water resistance. Some owners find the bracelet to be of cheaper construction with hollow links, and a few have reported quality control issues. The consensus is that the Seiko 5 Sports SKX series offers good value for its price, appealing to those who appreciate its tool-like nature and iconic lineage.
