Introduced in 2006, this timepiece wrote a new chapter in prestigious watch manufacture as the first ultra-thin mechanical watch for ladies.
The Ref. 4896, which sparkles in diamond studded white gold case and impressive guilloché night blue dial, belongs to the Calatrava collection, acclaimed for the timeless elegance of its round cases that have expressed the inimitable Patek Philippe style for nearly three-quarters of a century.
While the shape and proportion of the case remain true to the 1930s Calatrava style, Patek Philippe has paid particular attention to the design of the all-new dial. First and foremost, this exclusive dial stands out with its unique night blue hue, which is accented by the brushed satin strap and 18K gold case and hands.
The surface of the dial features a delicate guilloché pattern of concentric waves and is covered with several layers of blue lacquer, producing an incredible depth of color as the guilloché pattern shimmers through.
Overall, 12 separate lacquering, firing and polishing steps are needed to achieve this velvety, enigmatic dial. Like the rays of a star, the hour markers, coated with powdered silver, enliven the dial. The faceted dauphine hands are polished and the satin-finished, rhodium-plated side of the case enhances the glow of the dial and the fire of the 72 diamonds on the bezel. With these attributes, the Ref.4896 possesses the radiance of a formal evening watch but retains its sleekness and discreet elegance.
The Calatrava Ref. 4896 beats to the rhythm of the manually wound Patek Philippe caliber 16-250 movement which is ultra-thin and extremely compact (2.5 mm thick with a diameter of 16.3 mm). It displays the prestigious Geneva Seal, a hallmark of true excellence.
