What people say

Owners + reviewers, side by side

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

Citizen Promaster Skyhawk U830

The Citizen Promaster Skyhawk U830 is praised for its updated 43mm titanium case, legible memory-in-pixel display, and cleaner, less cluttered design compared to previous versions. Reviewers highlight its versatile contemporary look and enhanced functionality from the caliber U830, while owners appreciate the MIP display and screw-down caseback. Some users find the interface clunky and the face busy, particularly noting the "calendar" label and the lack of radio or GPS time synchronization, with one owner finding the 45mm size and busy subdials less useful for non-pilots. On balance, owners and reviewers rate the Citizen Promaster Skyhawk U830 highly for its impressive technology and improved legibility in a contemporary package.

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.
