Setting the time when crossing the international dateline:
• When crossing the international dateline in a westerly direction (you enter
the next day, regardless of the time of day), simply turn the time forward
to the new local time, and the date change will take place automatically.
• When crossing the international dateline in an easterly direction (you
enter the previous day, regardless of the time of day), you must likewise
set your watch forward to the new local time. However, your watch will
now indicate the wrong date (one day too many). This incorrect date
indication can be corrected by resetting the hands twice, by 12 hours on
each occasion:
• Setting the watch back by 12 hours during the afternoon between 2 pm
and 8 pm will prevent the perpetual calendar from advancing at midnight.
• Setting the watch back by another 12 hours the following morning
between 2 am and 11 am will synchronise the date display with the local
date.
Reading the time in the dark
Both the dial and the hour and minute hands of your watch have lumines-
cent elements that allow you to read the time effortlessly even in total
darkness.
Water-resistance
The water-resistance of IWC watches is stated in bar and not in metres.
Metres, which are often used elsewhere in the watch industry to indicate
water-resistance, cannot be equated with dive depth because of the test
procedures that are frequently used. Water-resistance shown in metres
provides no indication as to actual use of the watch in the presence of
moisture and wetness, and in or under water. Recommendations for use in
connection with the water-resistance of your watch can be found on the
Internet at www.iwc.com/water-resistance. Your authorised IWC Official
Agent will also be pleased to provide you with information.
