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-39

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.

From video reviewers

The 200m water resistance is a notable strength. Reviewers did not reach a consensus on any weaknesses.

Longines CONQUEST

Owners widely praise the Longines CONQUEST for its versatile, aesthetically pleasing design, comfortable wearability, and excellent value, with many highlighting its high-quality finishing and smooth winding action. Reviewers and owners alike note the watch's well-wearing size and blend of vintage and modern design elements. Some owners report the polished surfaces can be prone to scratches, and multiple sources flag the bracelet's lack of micro-adjustment as a significant drawback impacting fit. Lume quality is also a recurring point of criticism, with one reviewer noting only the black dial version appears to have lumed hands. Overall, owners and reviewers consider the Longines CONQUEST a highly versatile and well-built everyday sports watch offering significant value.

From video reviewers

The elegant gold dial is a notable aspect of the Longines CONQUEST. The quartz movement may be a drawback for collectors who prefer mechanical movements. Reviewers disagree on the standout feature, with one highlighting the gold dial and the other the Blue Sunburst dial.
