The night sky of the Northern Hemisphere rotates counter-clockwise showing the passage of
the sky relative to the meridian of Sirius (the brightest star second only to our own Sun).
The sidereal day of 23 hours, 56 minutes and 4.09892 seconds is measured by the passage
of the fixed star Sirius (indicated on the dial via a special arrow).
The waxing and waning of the moon is shown on a secondary dial,
displaying both lunation - the time between two full moons, which is on average 29 days,
12 hours, 44 minutes and 2.82 seconds - and the lunar day - the time between two passages
of the moon across its meridian, being 24 hours, 50 minutes and 28,328 seconds.
Celestial timepieces have been produced for some time,
but none so accurate as the Patek Philippe Celestial.
To create a watch that accurately measures moon-phase and solar time,
the master watchmakers at Patek Philippe used sophisticated computerization
to produce the single precise ratio out of 25 trillion ratio combinations.
Just how accurate is this watch The lunar day is accurate to 0.05 seconds per day,
18.385 seconds per year, or 30 minutes and 38.5 seconds per century.
The sidereal day is accurate to 0.088 seconds per sidereal day,
32,139 seconds per year, or 53 minutes and 33.9 seconds per century.
The moon phase is accurate to 6.51 seconds per lunation. A remarkable achievement indeed!
One crown at 2 o'clock winds the watch and sets the time,
the other at 4 o'clock sets the astronomical indications.
Each watch takes approximately 18 months to complete, and about 35 examples
are produced annually. The 301 individual watch parts are hand finished.
All steel components are bevelled and polished reducing friction at
wheel contact points thereby improving precision.
The automatic rotor is made in 22k gold.
All Celestials bear the Geneva seal -
testament to the state of the art manifested in each watch.
Brand New Complete with original box and papers etc.
