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 Black Ice Quartz Watch

Owners widely praise the CWC SBS Black Ice Quartz Watch for its legible, uncluttered dial, excellent Super-LumiNova lume, and robust build quality, noting its comfortable 12mm thickness and durable PVD coating. The bezel action is described as having zero back play, and the fixed lugs are appreciated for easy strap changes. One owner reported the lume is readable throughout the night, while another flagged a faulty mechanism requiring replacement and poor retailer customer service. The £700 price is considered high by some compared to similar quartz divers, leading to questions about its value. Overall, owners rate the CWC SBS Black Ice Quartz Watch highly for its bombproof, toolish design and practical aesthetics.

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.
