About the Defy Skyline family
The Defy Skyline was introduced in 2022 as a 41 mm sports watch with an integrated bracelet, a faceted bezel and a dial patterned with four-pointed stars. Its El Primero 3620 drives a small seconds hand that turns once every ten seconds, a nod to the tenth-of-a-second El Primero chronographs.
The family now includes 36 mm models, skeleton versions, chronographs with the El Primero 3600 and models in steel, ceramic, rose gold and platinum. Dealers identify the size, dial and material from the reference and check the bracelet and extra strap.
