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 Field series

The Seiko 5 Sports Field series is praised for its value, offering an accessible explorer-style watch with a GMT complication and excellent legibility thanks to LumiBrite on the dial and bezel. The watches feature a 41mm stainless steel case, 100m water resistance, and are powered by either the 4R36 or 4R34 movement, both with a 41-hour power reserve. One reviewer notes the inclusion of a compass bezel with a lumed pearl and fully lumed Arabic numerals on the dial for the non-GMT models. Overall, reviewers consider the Seiko 5 Sports Field GMT models good value under 500 euros.
