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.

Hamilton Jazzmaster Seaview Auto

Owners widely praise the Hamilton Jazzmaster Seaview Auto for its attractive design and comfortable wearability when paired with aftermarket straps like sailcloth. Accuracy varies, with one owner reporting gains of 15 seconds per day after seven years of wear, which improved to +/- 4 seconds per day after servicing and case replacement. Another user noted finish issues after minimal wear, questioning the material quality. The Hamilton Jazzmaster Seaview Auto is available with a 45mm stainless steel case, sapphire crystal, 300m water resistance, and an ETA 2824-2 movement, with prices around $500. On balance, owners value the Hamilton Jazzmaster Seaview Auto for its aesthetic appeal and strap versatility, though material durability can be a concern for some.
