Zelos Aventurine (sellita) owners widely praise the dial's star-like appearance and the bracelet's light-catching qualities. Some owners note sharp edges on the bracelet. The manual-wind movement is cited as inconvenient for resetting the date and moon phase. Overall, owners rate the Zelos Aventurine (sellita) highly for its gorgeous aventurine dial.

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.
