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 Sea Seiko Diver’s Watch 60th Anniversary Limited Edition

The Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition features a 40mm case, 300m water resistance, and a 72-hour power reserve from the Calibre 6R55 movement, distinguished by a grey bezel insert and a wave-patterned silvery-white dial. The clasp includes an improved diving suit extension. Owners note the MarineMaster case is comfortable and wearable. However, some owners criticize the 6R54 movement's accuracy, reporting deviations of +25/-15 seconds per day, and find the production number too large for a "limited" edition, deeming it too expensive. On balance, owners rate the Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition positively for its comfortable case and attractive dial, despite concerns regarding its price and movement accuracy.
