Excellence for eternity: Here is how the Perpetual Calendar works.

This masterfully designed mechanism automatically recognizes leap years and the lengths of months and thus calculates the day of the week for any given date in the future.
For the leap year our Senator Excellence Perpetual Calendar presents a new separate display beneath hour 12. The hand moves counter-clockwise across a scale of 1 to 4, ensuring unmistakable clarity for every year, not just the leap year, which is clearly marked by the number “4”. #glashutteoriginal #baselworld2017 #senator #excellence #perpetualcalendar #eternity #leapyear #masterpiece #beautiful #indicator #tradition #take #a #closer #look
