Meet the Zenith Defy El Primero 21, making its debut at BaselWorld 2017. This watch carries on the brand's legacy of exceptional chronographs, thanks to its impressive El Primero 9004 movement that can measure up to 1/100 of a second. Plus, it's a comeback for the Defy name at Zenith. One model in particular, the 49.9000.9004/78.R582, joined the collection in 2018. Its sleek black ceramic case and rubber strap with alligator inlay add a touch of modern luxury to this timepiece.
