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 Air Race Auto

Owners widely praise the Hamilton Khaki Aviation Air Race Auto for its legibility and practicality, with some appreciating its countdown bezel and GMT pointer. However, opinions on its design are split, with some calling it a "Frankenstein" and disliking the skeleton hands, while others find the hands suitable for a pilot watch. One owner notes the lume is underwhelming and the 44mm size may be too large for some wrists. The original strap is also described as uncomfortable and prone to water stains. On balance, owners value the Hamilton Khaki Aviation Air Race Auto for its legibility and practical features, despite a polarizing design and some comfort concerns.

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.
