The Zenith Defy El Primero 21 was introduced at BaselWorld 2017. Building upon the brand’s rich chronograph tradition, it is powered by the new El Primero 9004 movement, capable of measuring up to 1/100 of a second. In addition, it marks the return of the Defy name for Zenith.Reference 24.9000.9004/78.R582 has a ceramised aluminum case (44mm) and an openworked dial.Edit January of 2018 – I have updated the material to ceramic as per Zenith’s website.
