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.

Seiko 5 Sports SKX series

The Seiko 5 Sports SKX series is widely praised for its value, robust build, and powerful lume, with owners appreciating its comfortable bracelets and improved movement featuring hacking and hand-winding. Some owners find the original SKX models heavy and bulky, while others praise their ruggedness and iconic dive watch design. Reviewers note the 38mm models offer great value at around €350 and are exemplary gateway watches, though their 100m water resistance without a screw-down crown makes them unsuitable for diving. The Seiko 5 Sports SKX series is seen as a decent watch, especially under £200, but lacks the tool watch capabilities of the original SKX, missing a screw-down crown, bezel pip, and ISO rating. On balance, owners and reviewers rate the Seiko 5 Sports SKX series well for its blend of value, improved movement, and tool-watch aesthetic, despite some missing dive certifications.
