The Calatrava model has been the foundation of Patek Philippe’s time only wristwatches, and was first introduced to the market in 1932 with the legendary reference 96. Since that time, the model has been continuously upgraded and modernized, and in 2013, the brand released the reference 5227. The new model featured a 39mm diameter case, with the automatic 324 SC caliber featuring center seconds, and date. The reference is still retailed today and offered in 18 karat yellow, white, and pink gold. The case is classic Calatrava, but similar to their Officer’s style case, features an innovative hinged caseback. Patek Philippe spent two years to create the hidden hinged back to seamlessly integrate into the case so collectors can admire the well-finished movement within. An additional feature is the blank inside caseback, with the first series engraved “Patek Philippe”, however later examples have a blank interior giving owners an option to personalize themselves.
