What people say

Owners + reviewers, side by side

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

Redux Zero-Hour

Owners widely praise the Redux Courg Type 39MM for its robust, no-nonsense design and good overall quality, with a reliable Seiko NH53A movement keeping time well. The titanium case and crystal have shown scratch resistance, and the bezel action is described as tight by some. Reviewers note the proprietary RDXB1 or blue lume glows brilliantly, though briefly. Some owners flag the crown stem as flimsy and the unidirectional bezel as having some play. Overall, owners rate the Redux Courg Type 39MM highly for its functional tool-watch design and durable titanium construction.

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.
