The House’s Perspective
The Patek Philippe Diamond Ribbon Joaillerie watch has been updated with a new version in white gold and a larger diameter, going from 33.3 mm to 36.5 mm. This change highlights, even more, the sparkling diamond embellishments that encircle the case like twirling ribbons and the graduated diamonds spiraling on the dial. Despite its radiant exterior, the watch still features the ultra-thin self-winding caliber 240 movements, keeping its sleek and elegant profile.
