The Zenith Defy Skeleton 41 pairs the octagonal Defy Skyline case with an open-worked dial, inspired by the brand's four-pointed star. This watch is powered by caliber El Primero 3620 SK, a high-beat, self-winding movement with 1/10th of a seconds display at 6 o'clock. The version shown here has a black ceramic case; this was added to the collection in 2023.
