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 Prospex SPEEDTIMER

Owners widely praise the Seiko Prospex SPEEDTIMER's design, with specific mentions of its beautiful ice blue sundial and compact 39mm case size, which some note wears smaller than its specifications due to a short lug-to-lug distance. Reviewers highlight its racing-inspired aesthetic and versatility, with one owner finding the 39mm solar model a sturdy and reliable everyday watch with 100m water resistance. However, some owners question the value proposition, citing the $700 price for a solar quartz model and a thickness of 13mm, while others expressed a preference for automatic movements. On balance, owners and reviewers appreciate the Seiko Prospex SPEEDTIMER's attractive vintage-inspired design and compact wearability, though some debate its value and thickness for a solar quartz chronograph.

From video reviewers

The solar-powered chronograph movement is a key strength. The bracelet finishing is a potential area for improvement. Reviewers are split on whether the aesthetic successfully revives the spirit of the original "Pogue."
