Since 2013, the moon-phase indication has been a highly appreciated feature on ladies' watches, and Reference 7121J showcases this complication beautifully. Patek Philippe has reimagined this intricate mechanism, adding a white gold case and a stunning blue dial that resembles a starlit sky. The dial is adorned with a sunburst pattern that creates a subtle play of light, while the bezel sparkles with 132 brilliant-cut diamonds set in the exclusive Dentelle technique. At the heart of this jewelry-watch beats the manual winding Caliber 215 PS LU, the smallest Patek Philippe complicated movement that maintains an elegant case diameter of just 33 mm.
