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.

Yema Superman Tourbillon CMM.31 Limited Edition

Owners praise the Yema Superman Tourbillon CMM.31 Limited Edition as an incredible and crazy watch, appreciating its unnecessary tourbillon complication and impressive specifications at a remarkable price point. The titanium construction contributes to comfort despite the 43mm case size. One reviewer notes the bracelet clasp's extension system is somewhat crude. On balance, owners and reviewers rate the Yema Superman Tourbillon CMM.31 Limited Edition highly for its compelling tourbillon feature at an accessible price.
