This watch features: Silvered textured guilloche dial. Blued applied Roman numeral hour markers. Blued skeleton hands. Small seconds sub-dial at the 7 o'clock. This small seconds hand features the "Dead Seconds" complication. The Dead Seconds Complication:  With regular mechanical watch the beats per hour (vph) interpret into the frequency the seconds hand advances - giving the seconds hand the perception of smooth motion AKA "the sweep seconds hand". With the dead seconds complication the seconds hand jump every second (much like a quartz watch). This complication is achieved through am additional going-train driven by a second barrel. AP devised a system with two superimposed seconds-wheels driven by a "differential", one is free and moves steadily forward at the rate of the VPH, while the other carries wolf's teeth and moves in jerks – hence the jumping seconds. The new AP High Efficiency Direct-Impulse Escapement is proudly displayed on the dial side of the watch. The benefits of this new escapement are considerable: No need for lubrication on the pallet-stones. Detached single-beat escapement: A single impulse corresponds to
