Local time can be quickly and easily set, moving the hour hand an hour at a time using the crown, while the watch continues running, ensuring that the exact time is kept. Should the time change pass midnight, the date will change automatically backwards or forwards. Together with the red 24-hour hand, two 24-hour rings show a second and third time zone – the Patravi TravelTec can thus display the time in three locations in the world at the same time. The inner ring can be moved an hour at a time both forwards and backwards, using a brand new single push-button mechanism – a first in the history of watchmaking.
