What people say

Owners + reviewers, side by side

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

CWC E9 Quartz Diver Watch

The CWC E9 Quartz Diver Watch is praised for its historical significance, unique Jolly Roger dial, and military-spec build. Owners report it is thin, small, very legible, and has a satisfyingly easy-to-wind crown, with some noting its accuracy and clean lume application. However, the luminous paint on the Jolly Roger is described as low glow, and one owner reported their T20 model had an inaccurate quartz movement and a soft acrylic crystal that scratches easily. Some find the Jolly Roger design "out there," while others like its unique aesthetic. Some feel it is overpriced for its components, particularly the standard Ronda movement. Overall, owners rate the CWC E9 Quartz Diver Watch highly for its unique aesthetic and military-inspired build.

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.
