Swiss. 1975. 18K yellow gold case and band. 33mm case diameter. In 1932 Patek Philippe produced the first model of the Calatrava collection.

This timeless, understated watch is inspired by the minimalist principles of the Bauhaus school of art and architecture which adheres to the principle that form must follow function. The round case of the Calatrava reflects the circular form of the movement, and the clarity and legibility of its clear, pure dial. The 33mm 18kt yellow gold case houses calibre 215. This movement has a height of a mere 2.55 mm. The case and bracelet are solid 18kt yellow gold. The dial has a pleasing Clous de Paris dial.
