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.

Maen Skymaster 38 MKIII

The Maen Skymaster 38 MKIII is praised for its refined case, impressive fit and finish, and compact 38mm size, which offers a premium feel with a sharp, legible dial and well-executed applied markers. Reviewers note the sweet winding action and the vintage-inspired brown sunburst dial with dauphine hands and lollipop register pointers. The watch is powered by a manual-wind Sellita SW510Mb movement with a 63-hour power reserve. Accuracy figures vary, with one reviewer reporting +7 seconds per day and another stating a tolerance of +/-15 seconds per day. On balance, owners and reviewers appreciate the Maen Skymaster 38 MKIII for its refined vintage-inspired design and compact dimensions at its price point.

From video reviewers

The 38mm case size is a key strength for the Maen Skymaster 38 MKIII. Reviewers noted the excellent quality-price ratio for a Swiss-made chronograph.
