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 GMT Chrono Quartz

Owners praise the Hamilton Khaki Aviation X-Wind GMT Chrono Quartz for its sturdy build, 100-meter water resistance, and screw-down crown, with one owner noting outstanding fit, finish, and quality. The dial design is described as meticulous, featuring raised, brushed stainless steel indices and a downward-pointing triangle. However, some owners find the watch big and chunky, and its specific GMT and chronograph features are considered by some to be of limited practical use. Lume is described as good but not amazing, and the AR coating on the sapphire crystal is decent. Accuracy figures vary, with one owner reporting the watch gained 6 seconds in its first few days of wear. Overall, owners rate the Hamilton Khaki Aviation X-Wind GMT Chrono Quartz as a dependable and well-built travel watch, particularly for its robust construction and detailed dial design.

Yema Superman Slim CMM.20

Owners and reviewers praise the Yema Superman Slim CMM.20 for its appealing retro design, balanced 39mm case, and in-house CMM.20 micro-rotor movement, with some finding the fish scale bracelet attractive. Concerns exist regarding its $2500/€2,490 MSRP, with some owners questioning its value and noting the potential for QC issues or a "jittery" seconds hand attributed to the new movement. The bracelet's articulation and stamped clasp draw criticism, though some owners report it improves with wear. Overall, owners and reviewers appreciate the Yema Superman Slim CMM.20's vintage styling and unique micro-rotor movement, but its value proposition and some finishing details are points of contention.
