IWC Schaffhausen PORTUGIESER PERPETUAL CALENDAR Instrucciones De Manejo página 28

Setting when crossing the International Date Line:
• When crossing the International Date Line in a westerly direction (you en-
ter the next day, regardless of the time of day), simply turn the time for-
wards to the new local time, and the date change will take place
automatically.
• When crossing the International Date Line in an easterly direction (you en-
ter the previous day, regardless of the time of day), you must likewise set
your watch forwards 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 occa-
sion:
• Setting the watch back by 12 hours during the afternoon between 2 pm
and 8 pm will prevent the calendar from advancing at midnight.
• Setting the watch back another 12 hours the following morning between
2 am and 11 am will synchronise the date display with the local date.
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 pro-
vides 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.
To ensure that your watch continues to function perfectly, you should have it
checked by an IWC service centre at least once a year. Your watch should
also be tested after exposure to unusually harsh conditions. If the tests are
not carried out as stipulated, or if the watch is opened by unauthorised per-
sons, IWC will accept no warranty or liability claims.
