Longines VHP Perpetual Calendar
This watch is a product of advanced electronic and micro-mechanical
technologies for everyday use. The L546 VHP movement is 20 times
more precise than a conventional quartz movement, displaying the
hours, minutes, seconds and date, and showing on demand the num-
ber of the month followed by the leap-year cycle in Roman numerals I
to IV.
The perpetual calendar accounts for short and long months as well as
February 29 each leap year. The calendar is self-adjusting until the year
2100, which is not a leap-year. The watch has a sapphire-crystal glass
and is water-resistant.
How to use your Longines VHP Perpetual Calendar:

Normal running (1)
Time-zone setting (2): Turning the crown forwards or back moves the
hours-hand in one-hour steps without changing the minutes or sec-
onds.
Turn the crown to bring the hours-hand to the right time for the zone.
