• The watch is provided with a date function and is so designed that thedate
changes once every 24 hours. The date changes around 12 o’clock midnight. If
AM/PM is not properly set, the date will change around 12 o’clock noon.
1. Pull out the crown to the first click. (The second hand
continues moving and the accuracy of the watch is
unimpaired.)
2. The date can be set by turning the crown
counterclockwise. Turn it until the previous day’s
date appears.
Ex.) If today is the 5th of the month, first set the date to
”4” by turning the crown counterclockwise.

HOW TO SET THE TIME AND DATE
(FOR CAL. 4R35 AND 4R37)
• Thereisnoneedtoturnthecrownfurtherwhenthemainspringisfullywound.But
the crown can be turned without damaging the watch mechanism.
• Oncethewatchiswoundupfully,itoperatesforabout41hours.
• Ifthe watchisusedwithoutbeing woundupfully,gainorlossof thewatchmay

• If the watch has stopped with the mainspring unwound, winding the mainspring
with the crown will not start the watch immediately. This is because the main-
springtorque(force)islowatthebeginningofitswindingduetothecharacteristics
ofmechanicalwatches.  The second hand starts to move whenacertain degree
of strong torque is reached after the mainspring has been wound up.  However,
swinging the watch from side to side to forcibly turn the balance can start the
watch sooner.
