Time, Chronograph function. Black and glossy dial.
The Benrus Sky Chief is a true pilot's chronograph watch. They were built with purpose: for instance, the longer lines at 4, 8, and 12 at the minute totalizer were essential for flight navigation back then. This Sky Chief is powered by the more-sought after Valjoux 72 version. The stainless steel case is very sharp with highly visible bevels.
