Zenith and the Defy name have a long history, but the latest collection to take the name is adding some Extreme elements. The series is made up of three different variants, all of which arrive with a robust 45mm titanium case. One with black dial accents, a brushed and polished option with blue dial accents, and a rose-gold option with gold-plated accents. Each is powered by legendary El Primero 9004 automatic movement with a 1/100th of a second chronograph that you have to see to believe. Each timepiece comes with a matching titanium bracelet along with a rubber strap and a velcro strap.
