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.

KUOE ROYAL SMITH 90-006

Owners widely praise the KUOE ROYAL SMITH 90-006 for its visual appeal and sapphire crystal with AR coating. The watch functions correctly and keeps time at approximately +5 seconds per day on the wrist, powered by a Miyota 9039 movement. On balance, owners value the watch's aesthetics and specifications, though some question its overall value proposition.

From video reviewers

The watch's unique blend of modern and retro elements is a notable strength, with a textured ivory waffle dial and Breguet numerals giving it the look of a vintage watch from the 1950s and 1960s. A potential drawback is the ~$770 USD price point, which is significant for a microbrand. Reviewers disagree on the movement's accuracy, with one reviewer noting it is noisy and another describing it as a "Japanese-manufactured high beat premium automatic movement".
