The Zenith Defy El Primero 21 made its debut at BaselWorld 2017, continuing the brand's legacy of exceptional chronograph timepieces. Its impressive new El Primero 9004 movement can measure up to 1/100th of a second. This model also brings back the iconic Defy name for Zenith. The Reference 95.9002.9004/78.M9000 features a sleek titanium case (44mm) and a striking openworked dial with blue accents. To complement its modern look, it comes with a titanium bracelet. This particular style was added to the collection in 2018.
