By the early 1970s, Patek Philippe had already created numerous variations of the Calatrava. In 1973, however, it would come out with a design that would forever be associated with the collection; the "Clous de Paris" guilloche – or hobnail, as it is better known in English – bezel. In some ways, this represented a deviation from the Bauhaus principles that had informed the original design of the Reference 96, as the hobnail bezel served no functional purpose. Paired with a simple round case and straight lugs, however, it was absolutely stunning and only further enhanced the classic appeal of the Calatrava collection. Powered by the manually-wound Cal. 177 it was, of course, a time-only display, available with several different dial variations, including ones with Arabic and Roman numerals. The design proved so popular that it is still in production today in the form of the updated Ref. 5116 and Ref. 5119.
