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 HYDROCONQUEST MESH

Owners widely praise the Longines HYDROCONQUEST MESH for its eye-catching dial colors and impressive fit and finish at its price point, with some noting a well-regulated movement losing around 2 seconds per day and others seeing accuracy within COSC specifications. The tapered mesh bracelet is described as a clever execution with emphasized adjustability, offering a neat feature for wrist swelling. However, some owners criticize the bracelet's clasp for lacking on-the-fly micro-adjustments and the potential for pinching, while winding the screw-down crown is considered inconvenient by some. The lume is a point of contention, with one owner finding it disappointing and fading quickly, while another reports it as strong and long-lasting. Overall, owners rate the Longines HYDROCONQUEST MESH highly for its competitive pricing and versatile, modern retro aesthetic.
