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.

Praesidus Service Watch

Owners widely praise the Praesidus Service Watch for its 38mm size and solid build quality, with the domed crystal providing vintage distortion and the unbranded dial appealing to history enthusiasts. However, owners report jumpy hand sensitivity when setting the time. One owner experienced a scratchy crown and a noisy rotor on their DD-45, which persisted after warranty service and eventually led to the crown locking mid-way. Concerns about slow customer service and a negative reputation for Praesidus's support are also noted by owners. On balance, owners appreciate the vintage aesthetic and wearability of the Praesidus Service Watch, though persistent customer service issues temper enthusiasm.

From video reviewers

The 38mm case size is a strength for those preferring smaller watches. The dial may show slight discoloration or unevenness in finish.
