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 Type 300 Automatic

Owners praise the AVI-8 Spitfire Type 300 Automatic for its compelling designs and striking color schemes, with one owner noting the brand consistently prompts purchases. The $450 price point is considered good value, and the watch features a comfortable brown leather strap. However, the included NATO strap feels cheap and is too long for a 7" wrist. One owner reported inaccurate seconds hand movement, and the 15mm thick bronze case is noted as slightly thicker than expected. Overall, owners rate the AVI-8 Spitfire Type 300 Automatic highly for its unique designs and value at the price point, despite some minor strap and case thickness observations.

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.
