When we board an aeroplane, we are often travelling not only to another place, but also to a different time. We jump between time zones not only when travelling, however – many people have friends or relatives who live abroad, and our business contacts are often international, too.
If we wish to contact someone in another time zone, we find ourselves wondering what time it is there – is it early in the morning or late at night? Will my call prove to be a nuisance, or will it come just in time?
A quick glance at the MONDO provides the answer: it shows the local time zone in the 12-hour format plus another time zone of your choice in the 24-hour format.
While the central 12-hour display uses three hands, the outlying 24-hour display is based on the one-hand principle.
An artificial horizon divides the 24-hour ring into a day half and a night half. The positioning of the 24-hour display at the outermost edge of the dial gives the scale maximum resolution and makes it very easy to read. The delicate hand completes one complete rotation every 24 hours, thus showing clearly how far the day has progressed – and making unwanted wake-up calls a thing of the past.
