Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners and reviewers widely praise the Fortis Flieger F-39 for its robust build quality, excellent finishing often compared favorably to more expensive watches, and legible utilitarian dial with distinctive color accents. The watch is noted for its precise bidirectional bezel action, excellent lume, and comfortable wearability, with one owner reporting accuracy of 1 second fast per day. Some reviewers flag the 39mm case as wearing large due to its lug-to-lug distance, and the 38-hour power reserve of the Sellita SW 200-1 based UW-30 movement is cited as a limitation, though newer versions feature a 70-hour power reserve. Overall, owners and reviewers highly regard the Fortis Flieger F-39 for its tool watch aesthetic and impressive machining and build quality at its price point.
The 200m water resistance is a notable strength. Reviewers did not reach a consensus on any weaknesses.
The Longines Spirit Pilot Flyback is widely praised for its refined 39.5mm case size, improved wearability, and clean dial design, incorporating enthusiast feedback by removing the five stars and date. Reviewers and owners consistently highlight its exceptional finishing, well-acting ceramic bezel, and the value it offers. The manual-winding L792.4 column-wheel chronograph movement is COSC-certified and offers a power reserve of approximately 68 to 72 hours. Some owners expressed disappointment with the removal of the five stars from the dial, and one reviewer noted that some numerals are partially cut off by the subdials. The watch is priced around $5,350 to $5,550 USD. Overall, owners and reviewers rate the Longines Spirit Pilot Flyback highly for its improved dimensions, finishing, and value proposition.
