What people say

Owners + reviewers, side by side

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

AVI-8 Spitfire Smith Automatic

Owners praise the AVI-8 Spitfire Smith Automatic for its dial depth created by elevated numerals, a deeply signed buckle, and detailed case sides. The watch is also noted for being practically mark-free with no dings found, and comes with a barely worn brown leather AVI-8 OEM strap. On balance, owners rate the AVI-8 Spitfire Smith Automatic highly for its detailed finishing and pristine condition.

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.
