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 Presage Classic Series

The Seiko Presage Classic Series is widely praised for its sublime dial and hand finishing, with textured dials inspired by silk and elegantly curved hands. Owners and reviewers highlight the value proposition under $1,000, the comfortable wearability due to case proportions and slim appearance, and the robust 100m water resistance on several models. The 72-hour power reserve from the 6R51 or 6R55 automatic movements is a consistent positive note. However, one owner criticizes the pin and collar bracelet system as awful, and the 24-hour subdial is noted as potentially annoying by another. Accuracy figures for the 6R55 movement range from +25/-15 seconds per day to within -15/+25 seconds per day. On balance, owners and reviewers rate the Seiko Presage Classic Series highly for its exquisite dial work and strong value at its price point.
