Self-winding mechanical movement that allows simultaneous management of departure time, current time (i.e., the time in the city of the world we will be in), and date. By pulling out the crown two clicks, it is possible to adjust the time to 24 hours, visible through a small arched window at 12 o'clock, and all other hands except the second hand, which stops. This operation is used to set the current time before embarking on your next journey. One click from the closed position, and while the second hand continues to run, you can adjust the central hour hand (TZC=Time Zone Corrector) forwards or backwards to manage the time in the city where you have just landed. Furthermore, it is capable of managing not only the time but also the retrograde date, through a complex system of gears developed by IWC, which allows the date not only to advance but also to go back if you are crossing the International Date Line eastward.
