What people say

Owners + reviewers, side by side

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

Christopher Ward C1 Moonphase 37

Owners widely praise the Christopher Ward C1 Moonphase 37 for its aventurine dial and moon display, with one user awarding it a perfect score for its celestial theme. However, the lack of hour markers and lume-less hands make time-telling difficult, and hands can disappear against the dial. The COSC-certified movement averages +2.3 seconds per day, and the bracelet clasp is noted for comfort. The moonphase complication itself is reported by one owner to be inaccurate despite manufacturer attempts to correct it, though other users view such complications as primarily decorative. The 38-hour power reserve is considered short. Overall, owners rate the Christopher Ward C1 Moonphase 37 highly for its striking aventurine dial and moon focus, despite challenges with legibility and the practical accuracy of its moonphase complication.

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.
