Cincinnati Watch Company P-40 A-11 Pilot Black Automatic

Owners widely praise the Cincinnati Watch Company P-40 A-11 Pilot Black Automatic for its sharp finishing, textured pearlescent dial, and excellent lume. The simple, understated design and comfortable 38mm size are also frequently highlighted. Some owners note the bracelet lacks quick micro-adjustments and the quick-release spring bars can dig into the wrist.
