About the Defy El Primero 21 family
The Defy El Primero 21 was introduced in 2017 with the El Primero 9004, which has two separate regulating systems: one for the time at 5 Hz and one for the chronograph at 50 Hz. This lets the central chronograph hand make a full turn every second and measure to a hundredth of a second.
The catalog lists around sixty references in titanium, ceramic, carbon and rose gold, many with skeleton dials. Dealers identify the material and dial from the reference and check the chronograph functions and papers.
