What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Hamilton American Classic Ardmore Small

The Hamilton American Classic Ardmore Small is a quartz watch, and owners report accuracy variations from losing 10-11 seconds per week to gaining 10 seconds per week, which is considered within an acceptable range. While typically a women's model, owners find it wearable on smaller wrists with compatible strap options available online. One owner notes the manual wind is sensitive and the crown is slightly crooked. The modern Ardmore is not waterproof. Overall, owners appreciate the Hamilton American Classic Ardmore Small for its vintage aesthetic and wearability on smaller wrists.

Yema Superman Worldtime GMT

Owners widely praise the Yema Superman Worldtime GMT for its premium feel, unique bezel-lock mechanism, and attractive domed crystal. Some owners note the aluminum bezel insert is less desirable than ceramic and report the bracelet clasp can be stiff or difficult to open. Inconsistent quality control and poor customer service have been flagged by some owners. On balance, owners value the Yema Superman Worldtime GMT for its distinctive features and comfortable wearability.

From video reviewers

The "Coke" bezel and maxi dial are attractive design elements. The in-house automatic GMT movement is a French alternative to pricier GMTs.
