Operating instructions
Self-winding GMT & GMT Chronograph
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, depen-
ding on whether the hour hand is moved forwards or backwards.

The crown has 3 positions:

positioned against the case, the crown ensures that the watch is
water-resistant.
