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.

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.

The SRPE33 and SRPE39 models are noted for their attractive price, manta ray decorated dials, and excellent LumiBrite lume, though bezel alignment can be inconsistent. The SNJ029 is celebrated for its dynamic, colorful aesthetic, solar charging, and comfortable strap, making it ideal for outdoor adventures. Overall, the consensus is that Seiko Prospex Sea The Black Series models offer excellent value, with specific models lauded for their unique dials, quality finishing, and practical features like solar charging.
