El Primero is celebrating its 50th anniversary. An opportunity to unveil this cult movement in its modernised version, fitted in the emblematic Chronomaster. The new El Primero lineage is inaugurated with series of 250 titanium models featuring an original ceramic bezel and skeleton dial. Reinterpreted to ensure greater modularity, the El Primero 3600 calibre has been designed using the latest technologies, while preserving the DNA of the original movement. Also beating at the high frequency of 36,000 vibrations per hour, it measures and displays tenths of a second. Alongside the original El Primero, it will gradually be introduced on other models in the range and equipped with various functions.
