Hamilton Khaki Aviation X-Wind Auto chronovsYema Rallygraf Alpine Cup Series Limited Edition

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.

The Yema Rallygraf Alpine Cup Series Limited Edition is praised for its 39mm proportions, thin profile, and retro-modern vibe, with reviewers noting decent finishing for its price point. Owners highlight the sweeping chronograph hands and good lume, though the 24-hour subdial is considered by some to be useless. The use of a K1 mineral crystal instead of sapphire is flagged as a drawback by multiple sources, and one owner finds the diver-style clasp slightly out of place. Accuracy figures and winding feel are not discussed. Overall, owners and reviewers appreciate the Yema Rallygraf Alpine Cup Series Limited Edition for its stylish retro design and wearable dimensions at its $549 price.
