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.

Grand Seiko STGF359

Owners widely praise the Grand Seiko STGF359 for its elegant pairing with an engagement ring. Some owners find the 29mm case size too small for a man's wrist, while others suggest it can be worn by men with smaller wrists, recommending an in-person try-on. One owner notes potential date wheel misalignment requiring servicing. The bracelet has a maximum perimeter of 185mm, with extra links available. On balance, owners value the Grand Seiko STGF359 for its elegant aesthetic, though its small size is a point of consideration.

From video reviewers

The Grand Seiko STGF359 features a 9F quartz movement with exceptional accuracy, deviating by only +/−10 seconds per year. A drawback of the watch is its 40mm case size, which may be a concern for those with smaller wrists. Reviewers disagree on the type of movement, with one praising the 9F quartz and the other highlighting the spring drive movement.
