People travelling East, for example from London to Hong
Kong, should pull the crown out to position 2 and move
the hour hand forwards (in this case by 8 hours). The table
above can be used to calculate any time difference.
People travelling West, for example from London to New
York, should pull the crown out to position 2 and move the
hour hand backwards (in this case by 5 hours). The table
above can be used to calculate any time difference.
In both cases, the “24-hour” hand allows travellers to
read the time back home – London, in our example – at
a glance, using the 24-hour scale on the dial. The second
time zone – in this case Hong Kong or New York – is read
off the dial in the usual way.
Each time the hour hand crosses midnight, the date jumps
forwards or backwards, depending on whether the hour
hand is moved forwards or backwards.
