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 Ice Diver

Owners widely praise the Seiko Prospex Sea for its robust build, classic dive watch design, and excellent value, with many highlighting its strong lume and comfortable wearability. Reviewers consistently flag its superior bezel action and overall finishing as standout features for its price point. Some owners find the 43mm case size substantial, with one noting it felt big, thick, and heavy on a 6.5-inch wrist, though others consider it a perfect size. The movement's power reserve is noted as less than newer variants by one reviewer. Overall, owners and reviewers rate the Seiko Prospex Sea highly for its classic design and robust build at an accessible price.
