CRANKCASE INSTRUCTION MANUAL 05
USING THE CHRONOGRAPH
The chronograph includes three separate hands:
• The narrow hand on the main dial face counts seconds. One full rotation is
60 seconds.
• The hand on the sub dial at the left counts minutes. One full rotation is
30 minutes.
• The hand on the sub dial at the bottom counts 1/10 seconds. One full rotation
is 1 second. After 30 minutes, this hand works as an hour counter.
The chronograph is controlled with two push buttons:
• Button “A” stops and starts the timer.
• Button “B” has several functions. In addition to pausing the display at the
current split time (intermediate time), it makes the chronograph hands move
forward to the ongoing time being measured, and it resets the chronograph
hands to the zero position.
Before using the chronograph functions, make sure the crown is fully against the
case and not at one of the click positions used for setting time and date. The
three chronograph hands should align precisely at the zero position. If they do
not, see the section on
Adjusting the Chronograph Hands.
TO ADJUST THE TIME AND DATE FOR SUBSEQUENT SETTINGS,
USE THESE SHORT PROCEDURES
TO SET THE TIME
1. Pull the crown out to the second click position (b).
2. Turn the crown clockwise until you reach the correct time.
3. Push the crown back in. Gently turn the crown clockwise
until it screws back into the case.
TO SET THE DATE
1. Pull the crown out to the first click
position (a).
2. Turn the crown clockwise until you reach
the correct date. If the current time is
between 9 PM and midnight, set the date
to the following day. (This is necessary to
ensure the date display will normally
change at midnight instead of 12 noon.)
3. Push the crown back in. Gently turn the
crown clockwise until it screws back into
the case.
