ILLUSTRATIVE MECHANISM · HOME DISC AT 9

MONACO is the departure point. The animated route compares Prince Albert I’s 1906 voyage with Albert II’s 2006 retracing.

Set local time without disturbing home.

The central hands jump by whole hours. The 24-hour home disc stays fixed, and the date advances or retreats when local time crosses midnight.
