Citizen Promaster NavihawkvsYema Flygraf Bi-Compax French Air Force

The Citizen Promaster Navihawk is praised for its purposeful dial layout, often compared to an aircraft cockpit, with applied faceted hour markers featuring lume and a smooth, secure rotating slide-rule or compass bezel. Owners note its good value, with one expressing interest in purchasing the 40mm model due to its appeal. The watch is powered by Eco-Drive movements, including the F900 GPS timekeeping caliber and the H804 radio-controlled quartz chronograph with world timer functions, offering a range of accessible functions with a slight learning curve. The 48mm models feature fully brushed stainless steel cases with short lugs for wearability, while the 40mm version offers a more compact stainless steel case with a navy-coated bezel and yellow accents. Overall, owners and reviewers appreciate the Citizen Promaster Navihawk for its functional, cockpit-inspired design and the value offered by its Eco-Drive technology and multiple complications.

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.
