Audemars Piguet's new generation Royal Oak Perpetual Calendar 7138 is the first to use a crown to adjust all functions of the perpetual calendar by switching the crown's multiple gears, further solving the problem of previous perpetual calendars being difficult to adjust because of multiple calendars. Yes, you read that right, one crown to adjust all functions, Audemars Piguet's first, other famous watch perpetual calendars can't do it.

In the past, there were two main ways to adjust the perpetual calendar. Either the case has a hidden button, but the disadvantage is that you need to use a needle (or toothpick) to press it, which destroys the beauty of the case and is not conducive to waterproofing; or you use the crown to adjust it with one button, but the disadvantage is that you can only adjust it one day forward each time by twisting it. If you need to adjust it for half a year or several months, it is very troublesome. OK, now the Audemars Piguet Royal Oak Perpetual Calendar 7138 is here.
Making it easier to adjust the watch and keeping the case intact are the two most difficult problems for perpetual calendars. Even Patek Philippe, which is best at perpetual calendars/perpetual calendar timing, has not been able to solve this problem so far, and still relies on the hidden button in the case. Audemars Piguet's huge innovation in the perpetual calendar this time has made Patek Philippe's perpetual calendar watch inferior.
The crown positions of the Audemars Piguet Royal Oak Perpetual Calendar 7138 are as follows.
