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 SPEEDTIMER

Owners widely praise the Seiko Prospex SPEEDTIMER for its unique dial colors and vintage-inspired design, with many appreciating its compact 39mm case size and 100m or 200m water resistance. Reviewers and owners note the V192 solar movement’s power reserve indicator and its reliability, though some owners express a preference for automatic movements. One owner finds the $700 price for a solar quartz model expensive, while another criticizes the €860 price point and desires a thinner case and a bracelet with quick-release or micro-adjustment. On balance, owners and reviewers appreciate the Seiko Prospex SPEEDTIMER for its distinctive aesthetic and versatile wearability, despite some reservations about its price and case thickness.
