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.

LONGINES SPIRIT FLYBACK PROTOTYPE

Owners widely praise the Longines Spirit Flyback Prototype for its attractive finishing, COSC-certified movement, and value as a flyback chronograph. Reviewers highlight its refined 39.5mm case and simplified dial, while some owners appreciate the reduced thickness and improved wearability compared to larger variants, with a lug-to-lug distance noted as potentially long for smaller wrists. The watch features a 68-hour power reserve and a bespoke L791.4 movement. However, the case thickness is a consistent point of discussion, with multiple sources citing 17mm, though some reviewers suggest thoughtful design makes it wear closer to 13.5-14mm. Owners are split on the dial's aesthetic, with some preferring previous configurations with gold subdial rings and concentric textures over the current flat matte dial and cut-off numbers. The leather strap is also noted as stiff and pinching.
