The Exclusive JCAA03 Caliber powers the Epic SF24 Tourbillon and all its time indications. The time on the main dial is set via the crown located at the 4 o'clock position of the case. Once the hours and minutes have been set, the World Time Display is to be adjusted via the pusher dedicated to this purpose. With this done, the main dial and the second time zone display work together through a fully mechanical connection: as the main dial advances to the following hour, so does the split-flap hour display, making for a highly engineered audible and visible feat - not just when it is adjusted, but also once every hour, throughout its operation.
