Oh, come on! Look at this crazy thing! It’s a massive Patek with all kinds of insane crap including sapphire dials and a pressed metal chapter ring. There’s got to be a perpetual calendar in there and probably costs as much as a Ferrari.
Starting with the dial side it is easy to see this is not a typical dial. Instead there is a dial ring, or chapter ring, with markers for the hours, minutes, and the date. The chapter ring is actually a part of the dial coated via a blue metalization process. Four small round sapphire dials occupy most of the rest of the dial area. At 12 is the year dial that shows the leap year cycle of four years, at 3 are the months, at 6 is the moon phase indication, and at 9 are the days. Now, you might at first glance be inclined to think these small dials actually rotate but they do not. Instead there is a small black hand under each dial that highlights the appropriate markings on the stationary dials.
