Zenith has released a new version of the Defy Classic with a full overhaul of the watch in lightweight carbon fiber. Not only is the 41mm case constructed out of the material but the company has also used it to craft an integrated bracelet, which is a first for an automatic timepiece. This makes for a watch that weighs just 65 grams, half the weight of a Defy Classic with a titanium case and bracelet. As for the rest of the watch, the Defy Classic Carbon features an openworked dial with ruthenium-plated markers and hands, an Elite 670 SK automatic movement with a 48-hour power reserve, and a rubber bracelet option.
