In 2017, Zenith launched the Defy El Primero 21 at BaselWorld. It's a continuation of their impressive history in chronograph watches, now featuring the advanced El Primero 9004 movement that can measure up to 1/100 of a second. Not only that, it also brings back the iconic Defy name for Zenith. Fast forward to 2022, the collection welcomed the Zenith Defy El Primero 21 Chroma reference 49.9010.9004/01.R947. This particular Defy boasts a sleek white ceramic case with vibrant rainbow accents.
