Patek Philippe expands its range of elegant ladies' watches with a new version of the self-winding Calatrava Reference 4997 in rose gold decked out in purple – an original and refined color that perfectly matches the warm nuances of the precious metal and the diamond-set bezel. The dial base embossed with a concentric waves pattern is coated with more than fifty successive layers of translucent lacquer creating a fascinating depth effect. The shade of the dial is echoed by the purple calfskin strap with satinated finish and rose gold prong buckle. The case houses the ultra-thin self-winding Caliber 240.
