The Patek Philippe references 5115 and 5116 represent two of the most traditional interpretations of the Calatrava, celebrating the manufacture's rich heritage of elegant, manually wound dress watches. Introduced in the early 2000s, both references are powered by the renowned Calibre 215 PS, a slim, hand-finished movement that perfectly complements their refined proportions. While sharing the same mechanical foundation, each offers a distinct expression of classical Genevan watchmaking—the 5115 revives the iconic Clous de Paris hobnail bezel that has become synonymous with the Calatrava, while the 5116 adopts a sophisticated Officer-style case with a hinged back and applied Breguet numerals, inspired by vintage Patek Philippe timepieces.

Produced in a variety of precious metals, including yellow gold, white gold and rose gold, the 5115 and 5116 showcase two complementary philosophies of timeless elegance. The 5115 appeals through its understated purity and architectural bezel, whereas the 5116 offers a more traditionally styled aesthetic with enhanced historical character. Together, these references represent one of the last generations of manually wound Calatravas before larger cases and automatic movements became increasingly prominent, making them highly regarded by collectors for their classical proportions, exceptional craftsmanship and enduring sophistication.
