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‚Äôclock. Its modular design expands the scope of applications of the new chronograph caliber, providing future latitude for extra functions. “

I have no illusions of ever owning this time piece, but if I only could win the lottery once. Just once.
