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.

Zelos Spearfish GMT

The Zelos Spearfish GMT is widely praised for its exceptional value, with reviewers highlighting its superb finishing, flawless machining, and a tool-less micro-adjustment clasp that exceeds its price point. It features a La Joux-Perret G100 movement with a 68-hour power reserve, achieving an average accuracy of +2.6 seconds per day, or a Miyota 9075 movement offering flier-style GMT functionality. The 40mm case and bidirectional 48-click ceramic bezel are well-executed, though one reviewer noted a minor compromise in the end link fit. Overall, owners and reviewers rate the Zelos Spearfish GMT highly for its impressive finishing and value proposition.
