The Patek Philippe 5002 Sky Moon Tourbillon is one of the most popular modern day watches from Patek Philippe. This exotic, rare, and beautiful watch is presently worth more than $1.5 million. These watches feature one of the rarest complications ever introduced to a wristwatch. In the year 2000, the Sky Moon Tourbillion became the first ever double faced wristwatch that presents the complete nocturnal sky. The moon phases, movement of the stars, and moon’s orbit can be is displayed by the masterpiece. The minutes and hours in sidereal time are also displayed.
The acoustic representation of minutes, quarter hours, and hours make the Tourbillon a wristwatch with one of the most stunning functions. The repeater indicates the hour with a gong when the slide towards the left of the case is activated. This is followed by double strikes for quarter hours. Finally, a gong of higher tone indicates the number of minutes that have passed since the previous quarter hour. Inclusion of this complication within the extremely small volume of a wristwatch is considered by the horologists to be an extremely difficult task. This feature has been accomplished spectacularly in the Patek Philippe Sky Moon Tourbillon watches.
Patek Philippe is also known for their legendary perpetual calendars. This feature is also found in the Patek Philippe Tourbillion. It has a refined perpetual calendar that displays date with an automated fly back (retrograde) hand. The hand for date moves ahead everyday by one slot and returns to the start of the month scale after the end of the month. Unlike conventional system followed in most other wristwatches with perpetual calendar, the Patek Philippe Sky Moon Tourbillon uses a patented wheel mechanism that provides a high degree of accuracy in terms of hand positioning. There are four subsidiary dials for all other displays of the perpetual calendar. These dials display the moon age, month, leap year cycle, and days of the week.
The manually wound movement in the watch is a perfect example of high precision engineering that is made possible by as many as 694 individual parts. The aesthetically crafted case made up of platinum or 18k gold provides it effective protection. Watch enthusiasts love the wide case for the engraved Calatrava Crosses.
To date, the Patek Philippe 5002 Sky Moon Tourbillon is one of the most complicated regular productions from Patek Philippe. The complexity of these watches is a perfect example of the age old craftsmanship that is the hallmark of Patek Philippe.
