Push the crown back in. the minute digits flash on and off
for 1 minute.
While the seconds digits flash, push the crown back in pre-
cisely at an observatory time signal or when a reference
time source marks the exact minute: this will return the
seconds digits to zero.
check that the minute display corresponds to the exact time; if it does not,
add or substract a minute (see 2.2).
2.4 CORRECTING THE DATE AND THE MONTH
Note: the calendar is programmed to provide the exact date during a full
leap-year cycle of four years, thus requiring a correction every february 29
only.
Select the second-date function display.
seconds/date
38
Pull the crown out: next to the date, the seconds digits are
replaced by the month digit(s), with all digits flashing.
month/date
rotate the crown forward or backward: if rotated rapidly,
the month will change; if rotated slowly, the date will
change.
Push the crown back in: the seconds digits replace the
month.
Leap-year adjustments: the calendar is programmed to switch automati-
cally from february 28 to march 1; it will therefore have to be adjusted
manually every february 29 by moving the date back by one day, from
march 1 to february 29.
Please note: although the watch does not normally display the month, the
latter must of course be correctly set to enable the perpetual calendar to
function normally.
