Citizen Corso DiamondvsYema Flygraf Bi-Compax French Air Force

The Citizen Corso Diamond is widely praised for its attractive dial, with owners highlighting its sunburst silver or blue finishes and light-catching qualities. Its reliable Eco-Drive movement, offering solar-powered, maintenance-free operation, is a significant draw, as is its value proposition compared to higher-end brands. Owners also appreciate the sapphire crystal for its scratch resistance and the watch's overall sturdy, well-built feel. Some find the 41mm case size and 44-46mm lug-to-lug comfortable for daily wear, noting a 70s statement feel or Genta-inspired look, while others consider it too large or awkward on smaller wrists. Mixed opinions exist regarding the polished case finish, with some finding it too shiny and others praising its immaculate finishing. The band's lining has been described as unpleasant by some, and one owner noted inconsistent seconds hand alignment and a small date window.

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.
