The Zenith DEFY line is a collection that has been launched, discontinued, and resurrected several times by our friends at Le Locle through different periods of time. Originally released in 1969, the DEFY line has seen numerous facelifts and at one point it was responsible for almost killing Zenith taking the brand down an abyss from where it had to be later rescued by Mr. Biver's protégée Jean-Frederic Dufour —now CEO of Rolex.
