The Hamilton Khaki Aviation Pilot Day Date Auto is praised as a strong entry-level Swiss pilot watch. Reviewers note the 80-hour power reserve, hacking, and quick-set day and date functions. One owner observed the rotor spinning aggressively during hand-winding at certain angles, questioning potential service needs. The day display's proximity to the center pinion is a point of criticism, with a suggestion that a date-only function might have been preferable. Overall, owners rate the Hamilton Khaki Aviation Pilot Day Date Auto highly for its robust feature set and value as an accessible pilot watch.
Owners widely praise the Santurce Guaraguao Time Only — Automatic Pilot Watch as a versatile bargain with excellent specifications, highlighting its strap versatility, bright lume, good customer service, and packaging.
