What people say

Owners + reviewers, side by side

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

Marathon Arctic OSAR 41mm Automatic

The Marathon Arctic OSAR 41mm Automatic is noted for its comfortable wearability on wrists under 7 inches, with one owner finding the 41mm size perfect. Accuracy observations vary, with one owner reporting a consistent +1 second per day and another noting -20 seconds per day. The watch features a Sellita automatic movement and has dimensions of 14mm thickness and a 48mm lug-to-lug. Overall, owners appreciate the Marathon Arctic OSAR 41mm Automatic for its comfortable fit and Marathon's overall appeal.

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.
