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 Automatic Diver Watch

Owners widely praise the CWC E9 Automatic Diver Watch for its military-spec toughness and satisfyingly easy-to-wind crown, with one owner calling it a perfect reissue due to its thin case, small size, and legibility. Some owners appreciate its durability and value as a beater or summer watch, noting its solid bars are a military requirement and highlighting its significant wrist presence and unique "Jolly Roger" dial design. Critics find the CWC E9 Automatic Diver Watch overpriced for its mineral crystal and 60-click bezel, despite its military heritage and HAQ movement, and its luminous paint is noted as low glow. Overall, owners rate the CWC E9 Automatic Diver Watch highly for its military-spec toughness and wrist presence, despite some reservations about its value proposition.

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.
