Explore the Skyline in an all-new light

Drawing inspiration from modern cityscapes where structures and light are bound in a constantly moving interplay, the DEFY Skyline Skeleton opens a whole new world of possibilities to what a skeleton watch can be. Seamlessly integrating the open dial with an openworked version of the El Primero automatic movement, the DEFY Skyline Skeleton opens a new dimension of complexity and visual harmony that goes far beyond openworked.

Conceived for an ever-fast-moving world, the El Primero 3620 SK automatic high-frequency manufacture movement drives the 1/10th of a second hand directly from the escapement, which beats at 5Hz (36’000 VpH), making it a “natural” fraction-of-a-second indication. The DEFY Skyline Skeleton stands out as the first and only openworked watch to feature this exceptional function. It has a power reserve of 60 hours.
