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 3

The Zelos Spearfish 3 is widely praised for its exceptional finishing, with razor-sharp polish and flawless brushed transitions that owners feel exceed its price point. The 40mm case is noted for its wearability, and the La Joux-Perret G100 movement offers a 68-hour power reserve, with reported accuracy averaging +2.6 seconds per day. Reviewers highlight the exceptionally smooth bi-directional bezel and a tool-less micro-adjustment clasp described as best-in-class among microbrands. The sapphire sandwich construction and lumed bezel are also cited as desirable features. Overall, owners and reviewers rate the Zelos Spearfish 3 highly for its outstanding finishing and value at its price point.
