The Patek Philippe Calatrava is a line of formal dress watches manufactured by Patek Philippe, the premier Swiss watchmaker. Patek Philippe introduced the Calatrava to the world in 1932 as the result of an avant-garde philosophy of aesthetics that showcases smooth lines and subtle, but luxurious elegance and has continued to keep the timeless design of the Calatrava well into the next century.

Unlike other Patek Philippe watches, which are some of the most complicated in the Swiss watch industry, the Calatrava is very simple in design. Often, the Patek Philippe Calatrava watch only shows the date, hour, minute, and second with no other complications such as a chronograph. Some Calatravas are extra thin, with patterns of hobnail or very wide polished bezels - all unforgettable signs that these watches are Patek Philippe Calatravas.

As of 2010, the price of a Patek Philippe Calatrava is approximately $18,500 USD, making it one of the cheapest Patek Philippe watches available.
