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 Le Locle Open Heart

Owners widely praise the Tissot Le Locle Open Heart for its elegant aesthetic, featuring a guilloché dial and Roman numerals, and appreciate its practical 80-hour power reserve and Nivachron hairspring. The watch is also noted for offering dual bracelet and strap options, along with a see-through case back. However, one owner flags negative community feedback regarding the comfort of the synthetic leather strap. Overall, owners rate the Tissot Le Locle Open Heart highly for its attractive design and impressive technical specifications at its price point.
