The Zenith Defy Classic Blue Ceramic embodies the brand’s avant-garde spirit — blending futuristic design, high performance, and modern luxury into a striking timepiece. Crafted entirely from blue ceramic, the 41 mm case showcases a perfect interplay of satin-brushed and polished surfaces, offering both durability and a sleek, contemporary presence. The open-worked blue skeleton dial reveals the intricate mechanics of the Elite 670 SK automatic movement, highlighting Zenith’s mastery of precision and architectural watchmaking.

Luminous silver-tone hands and index markers ensure legibility amid the layered skeleton design, while the date display at 6 o’clock integrates seamlessly within the dial’s geometry. The watch is completed with a matching blue rubber strap and titanium folding clasp, balancing sporty versatility with refined comfort. Water-resistant to 100 meters, the Defy Classic is as functional as it is bold, powered by the Elite 670 calibre with a 50-hour power reserve and visible through the sapphire exhibition caseback.
