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.

Spinnaker Fleuss 40 Automatic

Owners find the Spinnaker Fleuss 40 Automatic a good size for smaller wrists, though one owner notes the lume is too diffuse for easy nighttime reading. The pilot-style crown is an unusual feature for a dive watch. Overall, owners value the Spinnaker Fleuss 40 Automatic for its wearability on smaller wrists.

From video reviewers

The coral red dial is a unique aesthetic. The watch is a strong contender for best-in-class under $300.
