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 Mechanical Datsun 240Z Limited Edition

The Seiko Prospex SPEEDTIMER Mechanical Datsun 240Z Limited Edition is praised for its vintage racing concept, applied markers, and dial that shifts from cream to silver with orange accents. Owners appreciate the Datsun logo, dual crowns, and internal countdown bezel, with some noting Seiko's finishing is top-notch. However, some find the dial text cluttered, particularly "automatic 3 days," and consider the price point too high. The watch features a 42mm black-coated stainless steel case, an external tachymeter bezel, and Seiko's 8R48 automatic chronograph movement with a 45-hour power reserve. On balance, owners rate the Seiko Prospex SPEEDTIMER Mechanical Datsun 240Z Limited Edition well for its unique vintage concept and quality finishing, though price remains a point of contention for some.
