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 Dumas Automatic

Owners widely praise the Spinnaker Dumas Automatic for its attractive textured blue dial, applied indices, and well-finished case, noting its comfortable wearability due to a short lug-to-lug distance. Some owners flag the use of mineral crystal instead of sapphire and a bracelet with a learning curve and loose keeper. Overall, owners rate the Spinnaker Dumas Automatic highly for its aesthetics and case finishing at its price point.
