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.

Maen Skymaster 38 MKIII

The Maen Skymaster 38 MKIII is praised for its refined case, impressive fit and finish, and compact 38mm size, which offers a premium feel with a sharp, legible dial and well-executed applied markers. Reviewers note the sweet winding action and the vintage-inspired brown sunburst dial with dauphine hands and lollipop register pointers. The watch is powered by a manual-wind Sellita SW510Mb movement with a 63-hour power reserve. Accuracy figures vary, with one reviewer reporting +7 seconds per day and another stating a tolerance of +/-15 seconds per day. On balance, owners and reviewers appreciate the Maen Skymaster 38 MKIII for its refined vintage-inspired design and compact dimensions at its price point.

From video reviewers

The 38mm case size is a key strength for the Maen Skymaster 38 MKIII. Reviewers noted the excellent quality-price ratio for a Swiss-made chronograph.
