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.

NOMOS Glashütte Ludwig automatic

Owners praise the NOMOS Glashütte Ludwig automatic for its exceptional blend of traditional Roman numerals and railroad tracks with modern design, highlighting fine details like the tiny logo on the crown and the exceptional dial printing. The long lugs are a significant consideration, with some finding the 35mm model wears larger and the 33mm a better fit for wrists around 6.5 inches. Overall, owners appreciate the NOMOS Glashütte Ludwig automatic for its unique aesthetic and attention to detail.
