In 2018, Zenith unveiled the Defy Classic at BaselWorld as an entry to their Defy series. This timepiece has a 41mm case and runs on the self-winding Elite 670 movement, upgraded with a silicon pallet lever and escape wheel. A new addition to the collection in 2020 is the Reference 10.9001.670/80.M9000, which boasts a carbon fiber case and bracelet to match.
