Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Fortis Flieger F-43 Bicompax for its excellent value, legible dial, and comfortable wearability despite its 43mm size, with some regretting selling theirs. The watch features 200m water resistance and an all-brushed finished case. However, some owners express concerns about current pricing being too high, with one noting a preference for 22mm lugs over the 20mm found on the watch. Overall, owners rate the Fortis Flieger F-43 Bicompax highly for its value and legibility.
The petrol dial is a strong point. The price point is significant.
Owners widely praise the Hamilton Jazzmaster Maestro Auto Chrono's premium case finishing and versatile dial layout, suitable for both casual and formal wear. Some owners note the 45mm size can be bulky and may not fit under shirt cuffs, and a lack of a second hand is a deal-breaker for some. Accuracy figures range from gaining about 5 seconds per day to keeping time within 10 seconds per day even after many years without service. Concerns exist regarding the serviceability and potential maintenance costs of the H-21 movement. Overall, owners rate the Hamilton Jazzmaster Maestro Auto Chrono highly for its substantial build quality and attractive design despite some size and movement serviceability considerations.
The Valjoux 7750 chronograph movement is cited as a strength. Reviewers noted the movement is not without flaws.
