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.

Sugess Tourbillon Master S454

Owners widely praise the Sugess Tourbillon Master S454 for its attractive dial finishing, sharp case edges, and the visual appeal of its genuine tourbillon, especially considering its price point. Specific strengths highlighted include a delicate 38mm size with 11.5mm thickness and a crisp winding feel. However, multiple owners note accuracy issues, with figures ranging from +6 to +11 seconds per day and one report of -12 seconds per day. Concerns are also raised about the movement's finishing upon close inspection, the lack of internal anti-reflective coating causing reflections, a small crown that makes winding cumbersome, and potential long-term durability and serviceability challenges. The 24-hour complication is not independently adjustable, and water resistance is limited to 50m. Overall, owners rate the Sugess Tourbillon Master S454 highly for its impressive tourbillon and finishing at the price, despite some noted accuracy and finishing caveats.

From video reviewers

The value proposition of a functional tourbillon movement under $600 is a significant strength. Reviewers noted issues with the bracelet and wearability.
