What is a Perpetual Calendar?
A perpetual calendar is a calendar mechanism which, unlike a simple calendar, automatically adjusts to the correct day of the month by accounting for the varying durations of each month, as well as self-correcting for the 29th of February during leap years. Audemars Piguet are said to have been the first to produce wristwatches with perpetual calendar and moon phases, in 1924. In 1925, Patek Philippe modified a lady?s pendant watch with perpetual calendar to produce the world?s first instantaneous changing perpetual calendar wristwatch with leap year indication.

Franck Muller
Passion, precision and innovation are the three essential qualities that highlight the creative genius of Franck Muller. For over ten years, the history of his watches has been marked by innumerable masterpieces and collections giving a contemporary style and spirit within the legendary universe of the Art of Watchmaking.
The important dates in Franck Muller?s watchmaking career include: 1983, the date in which he created the first watch signed "Franck Genève; 1992", which represents the founding of the company, the opening of the first Franck Muller store in the world and the invention of the most complicated wristwatch ever made in horological history; 1995, symbolizing the inauguration of the new Franck Muller administrative and production headquarters in Genthod, near Geneva, Switzerland.
The creation of the most complicated watch in the world in 1992?enriched by new functions in 1998 and hailed again as a world record?brought worldwide attention to the event and confirmed the international prestige of the company. Each year since a new and unique timepiece is launched? a world first again and again. Its complications so successfully combined set the horological world ablaze with delight. The forms, richer every year, continually reconfirm the creator?s unique style, immediately and undeniably recognizable.
Such new creations today are ?Casablanca?, ?Havana?, ?Master Banker? or ?Conquistador?, to name just a few, each a faithful retranscription of the creative talent of Franck Muller. Franck Muller?s masterpieces, veritable collectors timepieces, are today exhibited in the most prestigious cities of the world, from Europe to Asia as well as America, the Middle-East and Australia.
