[1] Known for its simple and elegant design, the Calatrava wristwatch has been a flagship model of Patek Philippe since its introduction.

[8][9] The watch was originally designed by Henri Stern soon after his father, a dial manufacturer, acquired Patek Philippe in 1932.

3919 was the most popular model in the Calatrava range, with its signature guilloché "Clous de Paris" bezel.

Some Calatravas (such as the 5227) feature a date function, whereas others (such as the 5116, 5119, 5120, 5123, 5196) display only hours and minutes and, in some cases, seconds (such as the 5026, 6119).

This watch, called "Calatravone" by Italian collectors due to its case size, features a stainless steel case, a two-tone silver dial and black enammeled Breguet numerals.
