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 as an excellent gateway watch, offering great value with a solid build and powerful lume. Owners widely report that the NH36 movement's accuracy is a "luck of the draw," with official specs allowing up to +/-40 seconds per day, though many experience +/-5 to 10 seconds. Some owners note the lack of a screw-down crown and 100m water resistance, while others highlight its ISO 6425 compliance, 200m water resistance, and screw-down crown as superior tool watch features. Some owners find the original SKX models heavier and bulkier than newer lines, while others praise its iconic, tough, and rugged dive watch design and proven durability. On balance, owners and reviewers rate the Seiko 5 Sports SKX series highly for its iconic, durable dive watch design and strong value proposition.
