The transparent case back reveals its Calibre El Primero 9004. The revolutionary 1/100th of a second chronograph calibre is not only visible through the case back, though, but also through the dial. One of the most striking elements of the Defy Extreme is the dodecagonal ring under the bezel, which extends to the dodecagonal case back.
This sporty, exclusive watch can be combined with a variety of bracelets and straps thanks to its quick-change system: for example, one in micro-blasted or polished and satin-finished titanium and one in rubber with a folding clasp to match the case, meaning you have the right accessory for any occasion.
