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 or disc 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.
The crown has 3 positions:
1.
Normal position (wearing position): when the crown is positioned
against the case, the crown ensures that the watch is water-resistant.
