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.

Attention to details
Gemsetting

Any gem chosen for use in a Patek Philippe case or bracelet – diamond, ruby, sapphire, emerald – will be the very finest of its kind, and comply with the Patek Philippe Seal’s strict criteria. At Patek Philippe, only the top D to G color range is used. The clarity of the diamonds is always of the desirable internally flawless grade (known as IF), and exhibits an immaculate cut. The precision of the cut is also vital in ensuring a regular and even setting. The task of the gemsetter is to place it perfectly, so that it shows to exquisite advantage and is of course secure. Patek Philippe gems are set in the time-honored way – by hand, never bonded with adhesive. The setter positions each precious stone in its mount, either in a bezel-setting where the gem is set by carefully folding in the metal collar (usually gold) that surrounds it, or in an invisible setting, where the gem has a groove on the underside that fits onto a hidden grid of rails. Gems must be placed level, pointing in the same direction and all at the same height, while ensuring an ultra-safe hold. Precision and regard for the shape and character of the gem is vital to bring out its beauty and achieve the brightest radiance and luster.
