Not a thorough answer but the underlying movement is their standard quartz perpetual movement implying it could support all the functionality of a standard perpetual calendar. So once you can set the date, month and year you should be all set. The year is actually calculated based not on the actual year but on the date of the last leap year. Don't know if it answers your question. I have only seen a gen of this once and played with it very briefly. If I remember correctly you can actually see years from leap year with second hand and month through the calendar.
