What people say

Owners + reviewers, side by side

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

Glycine Airman Bronze GMT

The Glycine Airman Bronze GMT is praised by some owners for its 39mm size and 200m water resistance, with one owner finding it a well-built and finished modern take on the original. However, one owner criticized the main 12-hour hand on the 24-hour dial, stating it made the watch difficult to use and broke the original bezel function, leading to a return. Overall, owners are split on the utility of the Glycine Airman Bronze GMT's 12-hour hand on its 24-hour dial.

Hamilton Khaki Aviation X-Wind Day Date Auto

Owners widely praise the Hamilton Khaki Aviation X-Wind Day Date Auto for its value, technical aesthetic, and versatile wearability with straps. Reviewers and owners alike highlight its excellent legibility, bold Arabic numerals, and the appeal of its pilot watch design, with many appreciating the 80-hour power reserve. Some owners find the crosswind calculation functions unnecessary, and there are mixed views on the dial's font usage and color matching. Lume is frequently noted as weak, and some find the size large or the left-handed crown and pusher setup uncomfortable. Accuracy figures range from gaining 6 seconds in a few days to approximately -6 seconds per day. Overall, owners rate the Hamilton Khaki Aviation X-Wind Day Date Auto highly for its impressive value and functional pilot watch design.

From video reviewers

The H-21 movement's 60-hour power reserve is a notable strength. The large 44mm case size was mentioned as a potential drawback.
