A triple calendar chronograph has how many parts?!

Today we're working on Tony's watch, a Montrose triple calendar chronograph from the 1950s with a Valjoux 72c movement inside. It belonged to his father, who used to wear it all the time, but at some point many, many years ago it stopped working. Can we fix it?
Join Stian for a full service and repair of this beautiful old watch, with a few digressions as we go along!
