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 Flygraf Bi-Compax French Air Force

Owners widely praise the Yema Flygraf Bi-Compax French Air Force for its attractive, toolish aesthetic and excellent quality for the price, noting the legible Type A dial and 40mm titanium case. However, the acrylic crystal scratches easily, and the titanium case is prone to marking. The mecha-quartz movement's chrono timer sweeps rather than ticks, and one owner questions the purpose of the oversized crown. The in-house Yema 2000 movement is accurate at +/- 10 seconds per day but has a 42-hour power reserve, and some owners express concerns regarding Yema's past quality control and customer service. On balance, owners rate the Yema Flygraf Bi-Compax French Air Force highly for its attractive design and value, despite concerns about material durability and brand service history.
