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.

Longines MASTER COLLECTION CHRONOGRAPH

Owners widely praise the Longines MASTER COLLECTION CHRONOGRAPH for its classic styling and excellent fit and finish. The dial is described as mesmerizing and legible, balancing class and complexity, contributing to comfortable wearability. One owner finds the column wheel chronograph and moon phase complication a good value around $2k, though notes the case finishing can appear homogenous and the chronograph hour counter sometimes does not reset perfectly. A specific variant's 3 bar water resistance is noted as a limitation, restricting it to less demanding environments. One owner identified the movement as a Valjoux 7751. Overall, owners rate the Longines MASTER COLLECTION CHRONOGRAPH highly for its attractive dial and value proposition, despite minor finishing and water resistance caveats.

From video reviewers

The polished steel case finishing and the elegant dial with Roman numerals and complications are praised. The bracelet's perceived lack of solid links and the overall high polish of the case were noted as potential drawbacks. Reviewers disagreed on the value proposition compared to other chronographs in the market.
