Ulysse Nardin Moonstruck Worldtimer, Manual

The second step is to adjust the current World Time or GMT (Greenwich near London). 

The correct setting of the GMT is important for an accurate indication of  tides and moon 

phase.
The correct World Time or GMT can be found with the help of online resources. 

Alternatively, it can be easily calculated when the time zone of your current location is 

known. The GMT chart printed in the appendix can be of assistance. Example :  The diffe-

rence between EST (Eastern Time in the USA) and GMT is five hours in the winter and four 

hours in the summer. If it is 10.15 am in Washington D.C. it is 3.15 pm (15.15) GMT during the 

winter months and 2.15 pm (14.15) GMT during the summer months.
In position D turn the crown, until the GMT position (London) at the bottom of the dial (the 

hour marker at the 6 o’clock position) aligns with the correct GMT on the 24-hour indicator 

on the sun disc. Now you have set the sun disc to show the correct phase of the day. Si-

multaneously the minute hand should be set to the correct time.

PLEASE NOTE:

 The current World Time or Greenwich Mean Time (GMT) is always in-

dicated on the dial’s 6 o’clock position, which corresponds with the small depiction of 

Europe and the British Isles on the Earth miniature in the center. Consequently, if 

the sun symbol is at 6 o’clock, the watch indicates noon in Greenwich.

SETTING OF CURRENT LOCAL TIME

The third step is to set the local time using the two pushers 1 and 2. Please take care for 

the correct setting of a.m. and p.m. While the hour hand is set in one-hour increments, 

neither the sun disc (GMT), nor the moon disc move, but the date changes when the hour 

hand is set past midnight.
The two pushers are also a practical way to adapt the Moonstruck to time zone changes 

during travels, or when daylight saving time is introduced or ending.

SETTING OF THE CURRENT DATE

The final step is to set the date by pulling the crown to position C and turning the date 

hand forward or backward (hand with luminous arrowhead) to the correct date. This works 

forward and backward and no other indications will be affected. Do not make date correc-

tions between 10.00 pm and 02.00 am. 

PLEASE NOTE:

 All date changes, that do not affect the positions of Sun and Moon, such 

as the leap to the 1st of the following month in months with only 30 days, or the date leaps 

at the end of February, should be adjusted exclusively with this function in position C! 

Otherwise, the moon phase would move as well and thus introduce an indication error.
