I went into the medical station of the exhibition and took a look. The doctors were on duty inside. They told me that they are here for normal medical treatment.

It is not only a rare structure that can switch between two time zones, but also one of the few tourbillon minute repeater watches with a power that can approach four days. Probably the most surprising thing is that the entire watch is completely self-made in the Panerai watch factory.
