Introduction

7340/1R
- Twenty~4
Self-winding

The Twenty~4 collection welcomes its very first complication: a perpetual calendar, one of Patek Philippe's most emblematic Grand Complications.

Thanks to ultra-thin self-winding 240 Q caliber, the non-gemset case has retained its elegant slimness. The calendar indications appear in three subdials, complemented by a moon-phase aperture, thus creating one of the most recognizable faces among Patek Philippe perpetual calendars.

The silver-toned dial is distinguished by its double vertically and horizontally satin-brushed finish reminiscent of shantung silk fabrics.

How to set the moonphase indicator?

A disc, decorated with golden stars and two golden moons against a blue or white background representing the sky, rotates within an aperture. The disc is cut from a wafer of corundum crystal (sapphire).

Gold was condensed onto the disc by means of a vacuum process through a photographic mask to create the shape of the moons and stars.  The aperture is cut at its upper edge in order to represent the lunar cycle.

During the first days of each lunation, the leading edge of a golden moon becomes visible as a crescent on the left of the aperture and appears to wax as it emerges beyond the curved edge of the aperture representing the lunar terminator.

Half way through the lunation, the moon appears full. It then wanes as it disappears behind the terminator on the right of the aperture.

As the moon vanishes, the second moon on the disc is ready to appear on the left.

How to set the leap year indicator

The leap year indicator informs you about the year cycle: leap year or non leap year. Leap years are identified with the Roman numeral IV or the Arabic numeral 4.
Please select a year and press "Calculate" to find the year cycle.
