Provenance: Amateur collection Note: Developed and patented by Patek Philippe in 1996, the annual calendar is an emblematic complication of the brand. In 2010, Patek Philippe associated this "in-house" complication with a steel watch for the first time: the Nautilus 5726. Initially marketed only with a leather strap, the model is offered with a steel bracelet from 2012 under the reference 5726/1A. Expert: Geoffroy ADER assisted by Justine LAMARRE
