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.

Studio Underd0g Watermelon (Gen3)

Owners widely praise the Studio Underd0g Watermelon (Gen3) for its fun, entrepreneurial, and affordable nature, with a design described as "Bauhaus meets Bugs Bunny." However, some find its colors a love-it-or-hate-it feature and others perceive the overall quality and finishing as a tier below comparable watches. Accuracy figures are not specified, but one owner found the watch too thick for their taste. The chronograph function has been noted as potentially sticky or jumpy. On balance, owners are divided on the Studio Underd0g Watermelon (Gen3), with opinions split between its unique design and perceived value for money.
