Patek Philippe introduced the “Calatrava” line in 1932. The historical beginnings of the name went back to the middle ages, during the war with the moors when a Spanish religious order of monks successfully defended the citadel at Calatrava. At the end of the 19th century Patek Philippe adopted the Spanish Knight for its brand symbol. The Stern brothers, who purchased the company and restored the Patek Philippe name, envisioned the Calatrava collection as their flagship line.
