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.

Aevig Thule GMT

Owners widely praise the Aevig Thule GMT for its 70s-inspired design, lightweight titanium case with a hardness coating, and the accurate NH34 movement running at 1-2 seconds fast per day. The watch also features fantastic AR coating, a quick-release bracelet, and excellent customer service. Some wish for sharper case angles and polished details to enhance its dressier appeal, and macro photos suggest potential irregularities on the hour markers. Overall, owners rate the Aevig Thule GMT highly for its vintage charm and practical features at an affordable price.
