Studio Underd0g Steffany BluevsYema Flygraf Bi-Compax French Air Force

Owners widely praise the Studio Underd0g Steffany Blue for its beautiful multilayer dial with a floating effect and vivid Super-LumiNova, with one owner finding it smaller and more beautiful than expected. The 37mm case wears nicely, though some find it slightly small for larger wrists. One owner notes the power reserve can fall short of the advertised 48 hours, sometimes lasting only about a day. Overall, owners rate the Studio Underd0g Steffany Blue highly for its striking dial and luminous display.

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.
