Accompanied by Patek Philippe Certificate of Origin dated 24 July 2006, leather file containing information and images of reference 5078, platinum glazed display back no. 4'330'475, wooden presentation box and outer packing.
The present watch has never been offered at auction before and is the first example of a reference 5078 to appear in public to date.
Manufacture of reference 5078 was launched in 2005, the model available only in platinum.
It is fitted with the ingenious calibre R 27 PS which impresses not only by its remarkable number of 342 parts but also by Patek Philippe's masterly performance of combining a micro-rotor and a minute repeating mechanism in a proportionally small 12 1/2''' movement.
It is furthermore incorporating a "Cathedral" repeating mechanism of this watch consisting of a high-tone and a low-tone gong. When the repeating is activated, first the hours are stroke by means of one of the two hammers on the low-tone gong, followed by the quarter hours with double strikes on both the low-tone and the high-tone gong, and finally the number of minutes which have elapsed since the last quarter-hour with one hammer on the high-tone gong.
The length of the gong in a standard repeating mechanism corresponds to almost precisely one turn in the movement whereas those of the "Cathedral" mechanism exceed the case circumference by at least one and a half, even two turns. Consequently, a much richer and fuller timbre is achieved.
