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

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.
