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 The Mimosa

Studio Underd0g The Mimosa is praised for its playful, layered dial design evoking a cocktail, its comfortable 38mm cushion case, and the tactile experience of its manual-wind Sellita SW210-1 movement. Reviewers appreciate the fun collaboration and the easter egg of the textured dial, finding it fitting for the watch's playful nature, and one owner notes its 10atm water resistance rating was proven by surviving a swim. Owners and reviewers consider its $1,300 price steep for the Sellita SW210-1 movement, with some wishing for more competitive pricing or questioning if it offers the best value. Overall, owners and reviewers rate Studio Underd0g The Mimosa highly for its unique, playful dial design and comfortable wearability.
