That’s a great feature for when you want to store your perpetual calendar without having to set all indications all over again, when you decide to wear it after some weeks and up to two months. Let’s have a closer look at this spectacular timepiece that incorporates two gear trains, two escapements, and a perpetual calendar, and all that in a relatively small 42mm case.
