What people say

Owners + reviewers, side by side

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

Hamilton Khaki Aviation Pilot Day Date Auto

The Hamilton Khaki Aviation Pilot Day Date Auto features an 80-hour power reserve and hacking, with quick-set day and date functions. One owner noted aggressive rotor spin during hand-winding at certain angles, questioning if service was needed. A reviewer criticized the day display's proximity to the center pinion, suggesting a date-only function would have been preferable. Overall, owners and reviewers find the Hamilton Khaki Aviation Pilot Day Date Auto offers practical complications and a substantial power reserve, though the day display's execution is a point of contention.

Lorier Hyperion SII

Owners widely praise the Lorier Hyperion SII for its vintage aesthetic, glossy black dial, and tasteful text. One owner notes the Miyota 9075 movement and calls it the best GMT under $800. Criticisms include a small GMT hand that is difficult to spot, and one user found the winding action not smooth with significant crown resistance. Overall, owners rate the Lorier Hyperion SII highly for its vintage aesthetic and value.
