Dual Time Functions / Precision - Ulysse Nardin Sonata Manual Del Usuario

DUAL TIME FUNCTIONS
Pusher 1 (+):
Each time the pusher 1 (+) is depressed, the hour hand jumps ex-
actly one hour forward.
Pusher 2 (-):
Each time pusher 2 (-) is depressed, the hour hand jumps exactly
one hour backward.
Remarks : The calendar indication is synchronized with the
pusher and changes automatically if a time zone adjustment is
made over midnight. Only press pushers to adjust local time when
the crown is in position A-1. Never activate both pushers together.
PRECISION
Precision and average daily rate depend on the activity of the
person wearing the instrument. Magnetic fields (computers, mobile
phones, etc.) may influence the working of a watch. Violent shocks
or knocks - quite common in tennis or golf - should be avoided to
prevent shaking that may loosen certain parts.
