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.

Hamilton Jazzmaster Slim Auto

The Hamilton Jazzmaster Slim Auto is praised for its elegance, light weight, and impressive leather strap, offering a classy yet engaging aesthetic. Its thin 8mm profile, achieved partly by omitting a seconds hand and utilizing the ETA 2892 movement, contributes to its wearability. However, one owner notes the 44mm case size as being very large, and another finds it less appealing than vintage Hamilton models, though the black dial version is considered better looking. Overall, owners appreciate the Hamilton Jazzmaster Slim Auto for its slim profile and elegant design.
