What people say

Owners + reviewers, side by side

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

Longines EVIDENZA

Owners widely praise the Longines EVIDENZA's distinctive tonneau shape, which offers a stylish alternative to round watches and is considered suitable for both dress and casual wear. Its detailing, including scalloped ridges and flamboyant styling, is frequently highlighted as spectacular and eye-catching, with particular admiration for the contrast between the steel case, brown strap, and blued hands. Some owners note the 6 numeral is cut off by the sub-dial, and one user wished the date and small seconds were positioned lower, though another found the date useful and well-placed. Accuracy is noted as being good, even after 20 years. Overall, owners rate the Longines EVIDENZA highly for its unique case shape and flamboyant styling.

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.
