Time Traveller allows you to see the time all over the world. The watch uses 16 landmark buildings to mark the time in different regions. You can read the local time by looking at the landmark building in your city or time-zone: for example if you're in London then you use Big Ben as your hour hand; in Paris you look to the Eiffel Tower or in New York you use the Statue of Liberty. A pigeon, the universal city dweller marks the minutes.
The watch uses a 24 hour mechanism which means the hour hand makes one rotation in 24 hours. This means you read it slightly differently from a regular (12 hour) watch: The upper semi-circle marks the hours from 6am to 6pm. When the hour hand is pointing horizontal left (9 o'clock on a regular watch) this corresponds to 6am. 12 noon is centre top and horizontal right is 6pm (3 o'clock on a 12 hour watch). The lower semi-circle marks the hours from 6pm back to 6am, with centre bottom marking midnight.
From a distance the hour hand appears to be a graphic motif, upon closer inspection it resolves to show the detail of the individual buildings.
