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 Lock Chronograph

Owners widely report AVI-8 watches offer a compelling design and are decently well made for the price. The AVI-8 Spitfire Lock Chronograph features a 42mm stainless steel case with curved lugs, a bi-compax meca-quartz movement, and a mineral crystal, with design elements inspired by Supermarine Spitfires. One owner notes that AVI-8 watches are "something different" and "decently well made," though not of "insane quality." On balance, owners and reviewers appreciate the AVI-8 Spitfire Lock Chronograph for its unique design and value proposition.

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.
