All time zones of the world in a single clock.
This clock consists in a central fixed bezel where it is possible to see the local time and external adjustable bezels according to the chosen time zone. The short hand marks the minutes, the longer hand marks the hours. The concept is based on the one hour gap intervals among one time zone and another.
Patented by Marco Poletti.
