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 Prospex Sea

Owners widely praise the Seiko Prospex Sea for its excellent value, robust build, and superb lume, with many appreciating its comfortable wearability due to its case shape and lug-to-lug distance. Reviewers consistently highlight its impressive finishing and classic dive watch design, often noting the bright LumiBrite lume. Some owners find the watch to be large, thick, and heavy, while others consider it the perfect size, indicating a split opinion on wearability for smaller wrists. The power reserve from some movements is noted as less than newer variants, and the clasp quality receives mixed feedback. Overall, owners and reviewers rate the Seiko Prospex Sea highly for its exceptional finishing and value proposition in the dive watch market.
