It is easy to find a quartz perpetual calendar. It is simply programed to know which months have 28-29-20-31 days. A true perpetual calendar mechanical watch is quite another matter. These are usually at least 15K.
Annual calendars, OTOH, are cheaper. The vast majority of them deal with 31 and 30 day months, but not Feb, so an adjustment is required every year. These are usually at least 5K.
I found a hybrid, a watch that knows all the months, including Feb, which is treats as a 28 day month, so it requires adjustment once every four years for a leap year. My dealer and I call this a "perennial calendar." Far more moderately priced.
You can see the date and the seconds hand in the subdial at 12. The Moonphases is at 3. The 30 minute subdial is at 9 as is the month, in French. The subdial at 6 shows the elapssed chrono hours and the day of the week, in French. The center second hand is the chrono second hand. Each element, day, date, month, and moonphase is independently adjustable via pushers recessed into the case.
It's big and heavy. The head alone weighs over 90g. The bracelet at least doubles that I think.
