Notes

A similar watch is published in "Patek Philippe Gen?ve, Wristwatches", by Martin Huber and Alan Banbery, 1998 Edition, p. 326.Ref. 5013 was until the introduction of the Sky Moon Tourbillon Ref. 5002 the most complicated wristwatch Patek Philippe produced. Self-winding, its movement consists of 515 parts and shares similarities with Ref. 5016, thethemanual-winding retrograde date perpetual calendar with tourbillon and 506 parts. Both watches incorporate perpetual calendar functions with a retrograde, or flyback, date hand whose specially developed mechanism absorbs almost no energy when the hand returns on the 1st of each month.Month and year indications in the leap year cycle will change instantaneously and if always kept running, no adjustments need to be made until Feb. 28, 2100 the moon phase indication will show a deviation of one single day only after 122 years and 45 days. Combining a minute repeater with a retrograde date function certainly sets this highly complex timepiece apart from other watches and a very small stamp on the balance bridge, the "Geneva Seal" or Geneva Quality Hallmark, makes a further important difference. It attests, that Ref. 5013 is produced according to the highest standards of watchmaking in the world.
