What people say

Owners + reviewers, side by side

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

CWC Automatic Divers Watch Mk.2 Black

Owners widely praise the CWC Automatic Divers Watch Mk.2 Black for its brushed chapter ring, precise 120-click bezel, clear sapphire crystal, excellent case finishing, and significantly improved lume. The watch is considered a terrific value with solid construction. Some owners express a preference for a matte finish for a more tool-like appearance, though polished versions offer a dressier look and easier scratch removal. On balance, owners rate the CWC Automatic Divers Watch Mk.2 Black highly for its tool-like features and excellent value.

From video reviewers

The bezel action is smooth. The price has increased due to popularity.

Seiko 5 Sports SKX series

Owners widely praise the Seiko 5 Sports SKX series for its iconic dive watch design, robust build, and excellent value, with many appreciating its timeless styling and tool-like character. The movement, while basic, is noted as offering hacking and hand-winding capabilities, and accuracy varies, with many owners reporting +/-5 to 10 seconds per day despite the movement's potential for +/-40 seconds. Some owners find the original SKX models heavier and bulkier than newer iterations, while others critique the lack of a screw-down crown and ISO rating on the newer Seiko 5 Sports SKX series, deeming it less of a serious tool watch. Overall, owners rate the Seiko 5 Sports SKX series highly for its enduring design and value proposition as a robust, everyday watch.
