What people say

Owners + reviewers, side by side

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

Fortis Flieger F-43 Bicompax

Owners widely praise the Fortis Original for its tool-watch aesthetic, legibility, and robust construction, with many noting excellent lume that lasts all night and precise day/date changes at midnight. The brushed stainless steel case is well-finished, and the 38mm size is considered comfortable and well-weighted despite being smaller than modern watches. Accuracy figures range from +2 seconds/day to +8 seconds/day, and some owners compare Fortis quality favorably to Omega. However, some users find the MSRP too high compared to brands like Sinn and Damasko, and one owner reported internal parts dislodging from a limited edition model. Concerns have also been raised about stripped lug screws on B-42 models and potential parts shortages due to past bankruptcy protection filings. Overall, owners rate the Fortis Original highly for its durable construction and tool-watch functionality at a competitive price point.

Zelos Vitesse

Owners widely praise the Zelos Vitesse for its vintage motorsport design and striking dial options, with particular appreciation for the salmon and panda configurations and their finishing. The bracelet, clasp, and overall value at $1200 are frequently highlighted as strong points. Some owners note the watch sits high on the wrist, and a few have observed minor cosmetic imperfections on subdials. The La Joux Perret L100 movement's accuracy varies, with one report of +5 seconds per day, and several owners find the winding action stiff and noisy, the pushers sticky, and the screw-down crown's feel underwhelming. On balance, owners rate the Zelos Vitesse highly for its captivating dial and strong value proposition, despite some reservations about the chronograph's operational feel and case height.
