What people say

Owners + reviewers, side by side

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

Bremont MBIII

The Bremont MBIII is praised for its versatile pilot's watch design, excellent dial visibility, and shock-resistant chronometer movement housed in a 43mm Trip-Tick case with a Faraday cage. Owners appreciate its unique origin story tied to Martin-Baker ejection seats and the brand's distinctive design language, with some noting the orange barrel accent. The watch features a 24-hour scale, 100m water resistance, and an improved Roto Click bezel. However, the "DANGER EJECTION SEAT" dial text is considered divisive, and its ETA 2892 GMT movement is not a "true" GMT as only the 24-hour hand is independently adjustable. On balance, owners and reviewers value the Bremont MBIII for its robust build and unique aviation-inspired narrative.

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.
