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 Auto Chrono

Owners widely praise the Hamilton Jazzmaster Auto Chrono for its excellent value, blend of classy and sporty design, and detailed dial with applied markers. The watch is noted for its impressive accuracy, with figures ranging from +0.5 to +3 seconds per day. Its 42mm case is described as a classic size with a mix of polished and brushed finishes, and the reverse panda dial is a particular highlight for some. However, the lume is consistently criticized as fading quickly and being underwhelming, and the internal bezel's functionality is found to be cumbersome. One owner found the watch too formal for their needs, while another noted the square case can wear larger than some alternatives. Overall, owners rate the Hamilton Jazzmaster Auto Chrono highly for its exceptional value and attractive, accurate timekeeping.

From video reviewers

The watch features a quality automatic chronograph movement. The date setting mechanism, requiring a specialized pusher tool, is a notable drawback. Reviewers disagreed on whether the watch competes effectively with luxury alternatives at its price point.
