#DefySkylineSkeleton: Visible from the front as well as the sapphire display back is the open-worked version of the high-frequency automatic El Primero calibre, the 3620 SK. Built with a similar architecture as the El Primero 3600 1/10th of a second chronograph and decorated in the same colour as the open dial, this automatic manufacture movement drives the 1/10th of a second hand directly from the 5Hz escapement. The automatic winding mechanism with bi-directional rotor with a star motif delivers a power reserve of approximately 60 hours.
