What people say

Owners + reviewers, side by side

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

Serica Ref. 8315 Travel Chronometer

Serica Ref. 8315 Travel Chronometer owners and reviewers praise its neo-vintage aesthetic, comfortable 39mm size, and unique day/night bezel design. Some find the lack of a date function a drawback, and the mirrored 12-hour bezel with AM/PM text is considered less practical than a traditional 24-hour bezel for time zone reading, with the lollipop-style 24-hour hand and asymmetrical bezel design also noted as potentially confusing. The watch is powered by a COSC-certified Soprod C125 movement with a 40-hour power reserve. One owner noted import duties and that the strap's aggressive taper required using the last hole for a proper fit. On balance, Serica Ref. 8315 Travel Chronometer is appreciated for its distinctive design and wearability, though its GMT functionality and bezel design are points of contention for some.

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.
