Patek Philippe Ref. 5304/301R-001 Minute Repeater with Retrograde Perpetual Calendar

The new rose gold version of this Patek Philippe Minute Repeater and Retrograde Perpetual Calendar watch is decorated with 80 baguette diamonds and belongs to the “Rare Handicrafts” series of the Geneva family. This new complication watch is equipped with a transparent sapphire crystal dial, and the wearer can admire the movement from the front of the watch.

The first Patek Philippe complication with a transparent sapphire crystal dial was designated as Ref. 2006 5104; it had a platinum case with rose gold appliques. From 2014 to 2018, closely followed by Ref. 5304 rose gold with white gold intarsia. Now, Patek Philippe has released a new version of rose gold high jewellery. Its bezel, lugs and folding clasp are shining under the fire of 80 flawless top Wesselton baguette diamonds (approximately 6.22 carats).

For this timepiece, Patek Philippe has developed an ingenious system that displays the day, month, and leap year cycle through a transparent sapphire crystal plate, where each display is highlighted in white and contrasts with the black background of the small hole below. To fix the extremely thin sapphire crystal disc on its tiny steel mandrel, a unique and patented assembly process must be developed.

The hollow black lacquered white gold leaf-shaped hands also enhance the visual effect of the movement and its steel parts. Its beveled and polished edges contrast with the rose gold plate decorated with pearl powder. The hand of the flyback date display has a crescent-shaped tip, and numbers are marked on the scale on the outermost edge of the dial. The perpetual calendar has a moon phase display and small seconds at 6 o’clock.

To further enhance the charm of this timepiece, Patek Philippe integrated exquisite platinum inlays and carved leaf patterns on the side of the case and the timekeeping slide.

The sapphire crystal caseback shows the magnificent view of the self-winding calibre R 27 PS QR LU movement, especially the minute repeater with two gongs or the centrifugal governor under the perforated Calatrava cross pattern. The rose gold embedded eccentric micro-rotor is decorated with leaf patterns and rhodium-plated sink. good website
