The more complicated variant of the original El Primero launched in 1969, featuring a triple calendar (day, date, month) and moonphase indicator in addition to the high-beat chronograph. While the 3019PHC had only date, this version added significant complexity while maintaining the revolutionary 36,000 vph frequency. Extremely rare today and highly sought after by collectors.
