What people say

Owners + reviewers, side by side

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

Praesidus A-11 Type 44

The Praesidus A-11 Type 44 is lauded for its faithful vintage aesthetic, featuring a domed acrylic crystal and coin-edge bezel, with its 38mm size offering a comfortable modern wear. It includes 100 meters of water resistance and a Swiss Soprod P024 movement with hacking and manual winding, assembled in the U.S. Some find the 32mm variant overpriced for its Landeron 21 movement, and the drilled lugs appear too close to the lug edge, though it keeps excellent time, gaining about 6 seconds per day, and feels substantial for its size despite a 13mm thickness. On balance, owners and reviewers appreciate the Praesidus A-11 Type 44 for its authentic vintage design and comfortable wearability at its price point.

Yema Flygraf Bi-Compax French Air Force

Owners widely praise the Yema Flygraf Bi-Compax French Air Force for its attractive, toolish aesthetic and excellent quality for the price, noting the legible Type A dial and 40mm titanium case. However, the acrylic crystal scratches easily, and the titanium case is prone to marking. The mecha-quartz movement's chrono timer sweeps rather than ticks, and one owner questions the purpose of the oversized crown. The in-house Yema 2000 movement is accurate at +/- 10 seconds per day but has a 42-hour power reserve, and some owners express concerns regarding Yema's past quality control and customer service. On balance, owners rate the Yema Flygraf Bi-Compax French Air Force highly for its attractive design and value, despite concerns about material durability and brand service history.
