Zenith Defy El Primero 21 Midnight Black Ceramic

The groundbreaking ZENITH DEFY EL PRIMERO 21 chronograph watch is now available in a Black Ceramic case that gives a perfect complement to its rich inner workings.

The DEFY EL PRIMERO 21 BLACK CERAMIC comes with a choice of a supremely comfortable black rubber strap with a matching black DLC-coated titanium double folding clasp, or a magnificently stylish black ceramic bracelet. With a generous 50-hour power reserve, this exceptional timepiece is water-resistant to 100 metres
