Automatic Winding Movement
A timepiece fitted with an automatic winding movement obtains the power to wind itself by the
movement of your wrist. It is important that your timepiece is adjusted to match the size of your wrist.
A loose fit may result in a loss in capacity of the timepiece to wind itself. When fully wound, your
timepiece has a power-reserve of approximately 42 hours. If the timepiece has not been worn for over
42 hours it is advised that it be manually wound to ensure necessary power-reserve.

Please note:
Before using the chronograph functions, please ensure that:
- the crown is in position I (= normal position).
- the two chronograph hands are precisely at zero position following activation of pusher B.
Should this not be the case, the positions of the hands must be adjusted (see the chapter
entitled “Adjusting the chronograph hands to zero position”).
Chronograph: Basic function
(Start / Stop / Reset)
1. Press pusher A to start the center stop-second hand.
2. To stop the timing, press pusher A again.
3. To reset the two chronograph hands to zero positioning, press pusher B.
Chronograph: Intermediate or interval timing
1. Press pusher A to start the center stop-second hand.
2. Press pusher B to stop the chronograph.
Note: Although the chronograph hands have stopped, the movement continues to record the
current timing.
3. Make up the measured time:
Press pusher B again and the 2 chronograph hands are quickly advanced to the ongoing
measured time. To continue to record intervals, continue to push pusher B.
4. Press pusher A to stop and the final time is displayed.
5. To reset the two chronograph hands to zero positioning, press pusher B.
Adjusting the chronograph hands to zero position (8371B)
1. Unscrew (if necessary) and pull crown out to position II (the two chronograph hands are in their
correct or incorrect zero position).
2. Press the pusher A two times with a time interval of 2 seconds. The hand counter at 9 makes a
turn.
3. Press pusher B continually for quick setting or push step by step to adjust the minute.
4. Press pusher A. The second hand makes a turn. Push B continually for quick setting and push step
by step to adjust the second.
5. Push and screw (if necessary) crown back to position I to exit.

Tachymeter Usage
The Tachymeter function is used to measure the rate of speed of an object over a fixed distance. The
scale, located either on the top ring or the inside bezel of the timepiece, will display speed in Miles,
Knots, or Kilometers per hour.
Example of usage: In a driving race, the car passes the first mile (km) post when the seconds hand
is at the 12:00 position (60 second mark). Commence measurement. At the 36 second mark the car
passes the second mile (km) post, you will see that the car traveled a distance of one mile at 100
miles (km) an hour.
2. Keep both pushers depressed simultaneously for at least 2 seconds (the second counter hand
rotates by 360°: corrective mode is activated.)
3. Adjust the second counter hand by pressing pusher A continually for quick setting or push step
by step to adjust the second.
4. Press pusher B to adjust next hand.
5. Adjust the minute counter by pressing pusher A continually for quick setting or step by step to
adjust the minute.
6. Push the crown back to position I to exit.

Water Resistance
See caseback for water resistance rating.
The water resistance rating provides guidelines for appropriate water-related exposure to avoid
damage to internal watch components. Please see chart for recommended usage guidelines.
In order to ensure water does not enter the watch and cause damage to it, please follow the
instructions listed below:
• Do not adjust the crown while the timepiece is in contact with water.
• Ensure the crown is in the closed position before contact with water. For timepieces with screw-
down crowns, ensure the crown is completely tightened before contact with water.
• For timepieces with pusher-enabled functionality, do not engage the function underwater.
• Exposure to extreme atmopheres is not recommended (i.e. hot water, saunas or steam rooms).
• Avoid exposure to water moving with force (i.e. water running from a faucet, ocean waves or
waterfalls).
• Avoid long exposure to salt water. After contact with salt water, rinse watch under tap water if
rated 5ATM or higher and wipe dry with a soft cloth.
