What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Astor + Banks Fortitude Pro

Owners and reviewers widely praise the Astor + Banks Fortitude Pro for its scratch-resistant coating, thin and compact 38.5mm case, and versatile dial options. The layered finishing with polished chamfers and comfortable bracelet are frequently highlighted as strong points, contributing to its wearability. One owner notes good timekeeping, while a reviewer states the Miyota 9015 movement is adjusted to +/-10 seconds per day. A potential drawback mentioned is the date numeral appearing in half shadow due to anti-magnetic shielding, and one owner considers the bracelet clasp dated. Overall, owners and reviewers rate the Astor + Banks Fortitude Pro highly for its durable construction and thoughtful design at its price point.

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.
