The best brand of them all, Patek Philippe, introduces a new automatic chronograph in a large platinum case (40.5mm, at least for PP this is large :-)), Ref. 5960P.“The movement is the new automatic caliber CH28-520 IRMQA24H with 40 jewels, a 55 hour power reserve and a flyback column-wheel, a power reserve indicator, an annual calendar, and day/night display. The rotor is 21kt gold. And, like all Patek Philippe mechanical movements, this new caliber has been awarded the prestigious Geneva Seal.The patented Patek Philippe Annual Calendar is a full calendar that automatically recognizes months with 30 and 31 days and, assuming that the watch is always running, only needs to be manually corrected once a year on March 1. It displays the day of the week, the date, and the month in three apertures, and it also controls the day/night indicator at 6 o???clock. Its modular design expands the scope of applications of the new chronograph caliber, providing future latitude for extra functions. “Source: Jorge Merino @ TZI have no illusions of ever owning this time piece, but if I only could win the lottery once.
