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.
Owners widely praise the Studio Underd0g Salmon for its unique, two-layered dial inspired by salmon skin, featuring a radially brushed metallic orange-pink lower part and a coarse, silvery dégradé shimmer upper part. The watch is powered by a decorated Swiss mono pusher movement with silky smooth winding, blued screws, and anthracite bridges, which one owner finds impressive. Accuracy is reported at ±5 seconds per day. Some owners find the £1700-£1800 price point difficult, especially given styling similarities to previous models. Overall, owners and reviewers rate the Studio Underd0g Salmon highly for its distinctive dial design and well-finished, smooth-winding monopusher movement.
