What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

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.

Zelos Comet 39

Owners widely praise the Zelos Comet 39 for its wearable 39mm size, thin profile under 10mm thanks to its manual-wind Sellita SW215 movement, and its captivating dial with a deep starburst effect. The winding action is described as a joy, and the watch is considered a stunner for its price, blending modern and vintage aesthetics. Some owners note frustration with Zelos's limited production runs leading to quick sell-outs. One owner found the logo childlike, while another experienced strap-rubbing issues with the short lugs, which were resolved with a Milanese bracelet. Overall, owners and reviewers rate the Zelos Comet 39 highly for its excellent value and striking dial design.
