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.

KUOE OLD SMITH 90-001

KUOE OLD SMITH is widely praised for its vintage aesthetic and comfortable 35mm wearability, with owners noting its attractive bronze case and dial contrast. Reviewers and owners alike highlight its excellent accuracy. However, the case finishing is considered average for the price, and the lume fades quickly. Some find the small date window difficult to read, and the Seiko NH38 movement is described as noisy. The 18mm lug width and PVD-coated strap hardware are also noted as drawbacks. Overall, owners and reviewers find the KUOE OLD SMITH to be a compelling vintage field watch offering good value, particularly for its aesthetic appeal and accuracy.
