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.

Tissot PRX

The Tissot PRX is widely praised for its exceptional finishing, comfortable wearability, and strong value proposition, with owners and reviewers highlighting its luxurious feel for the price. The integrated bracelet, often noted for its shine, finishing, and brushed surfaces with polished edges, is a significant draw, as is the watch's neo-vintage aesthetic and refined dial pattern. The slim case profile, measuring around 10.5mm to 11mm depending on the source, contributes to its comfortable daily wear, and the 100m water resistance is a practical feature. While one owner reported specific issues with a PRX Chronograph's hands and quality control after service, other sources focus on the Powermatic 80's reliable automatic movement and the overall joy of wearing the Tissot PRX. Some find sizing the bracelet challenging due to the lack of a micro-adjustment option.

From video reviewers

The Powermatic 80 movement with its 80-hour power reserve is consistently praised. The lume brightness is noted as a weakness. Reviewers disagree on the suitability of the lug-to-lug fit for smaller wrists.
