What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Christopher Ward C60 Trident Reef

Owners widely praise the Christopher Ward C60 Trident Reef for its fun, affordable design, vibrant multi-layered dials inspired by reef art, and good wearability due to curved lugs and a thin profile, with the 41mm size noted as better proportioned. The watch is powered by the Sellita SW200-1 movement and offers 200m water resistance, with pricing starting at £695. One reviewer suggested swapping the yellow minute hand and strap on a specific model for a different aesthetic. Overall, owners and reviewers rate the Christopher Ward C60 Trident Reef highly for its vibrant design and value at the price point.

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.
