What people say

Owners + reviewers, side by side

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

CWC RN Quartz Divers Watch Mk.2, Matte Top

Owners widely praise the CWC RN Quartz Divers Watch Mk.2, Matte Top for its excellent matte case finishing, precise seconds hand alignment, and dial reminiscent of vintage military watches. The Mk.2 upgrades, including a sapphire crystal, improved lume, and a precise 120-click bezel described as perfection with no play, are consistently highlighted as significant improvements over earlier versions. One owner noted the quartz movement gained 8 seconds over several months. Overall, owners rate the CWC RN Quartz Divers Watch Mk.2, Matte Top highly for its solid construction, military significance, and terrific value.

Seiko 5 Sports SKX series

The Seiko 5 Sports SKX series is widely praised for its value, robust build, and powerful lume, with owners appreciating its comfortable bracelets and improved movement featuring hacking and hand-winding. Some owners find the original SKX models heavy and bulky, while others praise their ruggedness and iconic dive watch design. Reviewers note the 38mm models offer great value at around €350 and are exemplary gateway watches, though their 100m water resistance without a screw-down crown makes them unsuitable for diving. The Seiko 5 Sports SKX series is seen as a decent watch, especially under £200, but lacks the tool watch capabilities of the original SKX, missing a screw-down crown, bezel pip, and ISO rating. On balance, owners and reviewers rate the Seiko 5 Sports SKX series well for its blend of value, improved movement, and tool-watch aesthetic, despite some missing dive certifications.
