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.

Maen Grand Tonneau Jump Hour

Owners widely praise the Maen Grand Tonneau Jump Hour for its unique style and accessible price point for a jump hour complication, with one owner finding the red dial variant looks and wears great. However, some find the hour and minute windows, particularly the minute window, too small and the font illegible, impacting legibility. Criticism also centers on the use of a Chinese Seagull movement in a watch priced over $1,000, leading some to label it a "fashion watch" and a "scam," while others note it is selling for significantly over its original price and is not worth it. On balance, owners are split on the Maen Grand Tonneau Jump Hour, with its unique design and value proposition countered by concerns over legibility and movement choice at its price point.

From video reviewers

The watch is praised for its ultra-thin profile and classic design. Reviewers noted the unique jumping hour complication.
