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.

Grand Seiko SBGX353

The Grand Seiko SBGX353 is widely praised for its mesmerizing "Skyflake" textured blue dial, considered by owners to be "perfect art." Reviewers and owners alike highlight the watch's elegant 34mm case size and the advanced 9F61 quartz movement, noting its exceptional ±10 seconds per year accuracy and precise second-hand alignment. Some owners find the dial's aesthetic appeal slightly diminished when worn compared to other options, and one owner replaced the quick-release buckle for a Hirsch clasp. Overall, owners rate the Grand Seiko SBGX353 highly for its exquisite dial finishing and the precision of its quartz movement at its price point.
