What people say

Owners + reviewers, side by side

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

Audaz Reef Diver

The Audaz Reef Diver is described as a bold, rugged, and dependable tool watch with a focus on clarity and accuracy for diving. It features a 45mm 316L stainless steel case, sapphire crystal, Super-LumiNova C3, and 300m water resistance. One owner notes it is a large, heavy watch. The Audaz Reef Diver is powered by a Seiko NH35 automatic movement and is priced starting at $269. Overall, owners and reviewers view the Audaz Reef Diver positively as a robust tool watch with a clear dial and strong water resistance for its price.

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.
