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 Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation

The Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation is noted for its refined, slimmed-down 39.5mm stainless steel case with a "super hard" coating and a box-shaped sapphire crystal. It offers 200 meters of water resistance and is powered by the slim Caliber 6L37 automatic movement, which has a 46-hour power reserve and an accuracy rating of -10/+15 seconds per day. Reviewers highlight its wearability and functionality as a dive watch, with one noting it as Seiko's thinnest diver ever at 12.3mm. However, concerns are raised about Seiko's continued reliance on the 62MAS design, with one reviewer wishing the Marinemaster remained a separate line, and the bracelet's end-links appearing mismatched in initial images. Its price of A$4,650 is considered high given its specifications compared to competitors.
