What people say

Owners + reviewers, side by side

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

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.

Tornek-Rayville Blakjak Time-elapse

The Tornek-Rayville Blakjak Time-elapse is a rugged, dive-capable field watch, an evolution of a 1990s military concept. It features a 42.5mm stainless steel case, a sapphire crystal, and a Seiko NH36 automatic movement with a 40-hour power reserve. The dial is busy but functional, and the watch features Super-LumiNova BGW9. On balance, reviewers note the Tornek-Rayville Blakjak Time-elapse is a modernized military watch with robust dive capabilities.
