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-39 Werk 7

The Fortis Flieger is widely praised for its superb readability, robust build quality, and phenomenal fit and finish, with reviewers noting the practical Type-A dial and utilitarian design. The F-39 models are noted to wear large due to their lug-to-lug distance, and the UW-30 movement offers a 38-hour power reserve, while other variants feature a 70-hour power reserve. On balance, reviewers highlight the Fortis Flieger's modern, stylish take on pilot's watches, balancing legibility with unique aesthetics.

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.
