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 X-Wind Auto chrono

Owners widely praise the Hamilton Khaki Aviation X-Wind Auto chrono for its good quality for the price and versatility with straps. Reviewers highlight its unique drift angle calculator function as a horological curio and legitimate navigational tool, noting its modified Valjoux 7750 movement provides a 60-hour power reserve. Some owners find the busy dial and left-handed crown/pusher setup unusual, and its lume could be stronger, while others consider it a heavy travel watch with features not useful for everyday use. On balance, owners and reviewers rate the Hamilton Khaki Aviation X-Wind Auto chrono highly for its functionality and build quality at its price point.

Lorier Hyperion SII

Owners widely praise the Lorier Hyperion SII for its vintage aesthetic, glossy black dial, and tasteful text. One owner notes the Miyota 9075 movement and calls it the best GMT under $800. Criticisms include a small GMT hand that is difficult to spot, and one user found the winding action not smooth with significant crown resistance. Overall, owners rate the Lorier Hyperion SII highly for its vintage aesthetic and value.
