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 5 Sports Field series

The Seiko 5 Sports Field series offers an accessible explorer-style watch with a 41mm stainless steel case, 100m water resistance, and a Hardlex crystal. The Field GMT model features a caller GMT complication powered by the 4R34 movement, while the standard Field models use the 4R36 with a 41-hour power reserve. Both models include Arabic numerals coated in LumiBrite and a lumed pearl on the bezel. On balance, the Seiko 5 Sports Field GMT is a well-regarded entry-level explorer watch for its price point, despite its office-style GMT function.

From video reviewers

The prominent five-sided GMT hand enhances legibility and adds a sophisticated aesthetic to the watch. The Seiko 5 Sports Field series offers similar functionality to the Explorer 2 at a lower price, making it a valuable option. Reviewers disagree on whether it's a missed opportunity for Seiko to release this model first, with one reviewer implying it would have been a more logical addition to their lineup.
