Chronograph Functions

•  The minute counter measures 30 minutes per rotation.
•  The centre stop-second measures 60 seconds per rotation.
•  The 1/10 second counter measures 1 second per rotation. After 30 minutes, this counter works as an hour counter. The hour counter measures 10 hours per rotation.

Note:
Before using the chronograph functions, please ensure that:

•  The crown is in position I (normal position).
•  The 3 chronograph hands are precisely at zero position following the activation of pushbutton B. Should this not be the case, the positions of the hands must be adjusted (see “Setting the Chronograph Hands to Zero Position”).

Chronograph: Basic Function (Start/Stop/Reset)

5. Reset To reset, press pushbutton B. The three chronograph hands are returned to their zero positions.

Chronograph: Intermediate or Interval Timing
This function enables you to stop the hands in order to read an intermediate time without interrupting the timing operation. Once you restart, the hands will automatically catch up with the ongoing elapsed time.

1. Start Press pushbutton A to start.
2. Display an Interval Press pushbutton B to stop momentarily to read an intermediate time (while timing continues in the background).
3. Make up the Measured Time Press pushbutton B again to catch up with the ongoing elapsed time.
4. The three chronograph hands quickly advance to the ongoing measured time.
5. Stop Press pushbutton A to stop timing. The final time is displayed. Reset Press pushbutton B to reset the three chronograph displays to zero positions.

Setting the Chronograph Hands to Zero Position
When one or several chronograph hands are not in their correct zero positions and need to be adjusted (e.g. following a battery change), the timers can be set to zero by the following steps:

1. Pull out the crown to position III. Then, the 3 chronograph hands may move to their correct or incorrect positions.
2. Keep pressing pushbutton A and B simultaneously for at least 2 seconds. As the centre stop-second rotates by 360º, the corrective mode is activated.

To adjust the Centre Stop-second, make a short press on the pushbutton A to move the hand in a short single movement and/or make a long press on pushbutton A for a long continuous movement. After finishing the adjustment, press pushbutton B to switch to the next hand.

Pull out the crown completely onto position II and set the time by turning the crown towards the desired direction. Once finished, push the crown back onto position I.

Manual Winding

•  This watch is equipped with a manual winding movement manufactured in Switzerland.
•  To do that, turn the crown clockwise while on position I until the movement is fully winded.
•  To ensure that the watch does not stop, we recommend regularly winding it once a day.

CAUTION:
Do not force on the crown once the movement is fully winded, as this could damage the movement.

1.  Normal position (not pulled out)
2.  Half pulled out
3.  Completely pulled out

Restarting the Automatic Watches
An automatic watch is wound by the movement of your wrist. If the watch has remained off the wrist for more than 40 hours and has stopped, it is advisable to wind it manually. To do so:

1. Set the crown into position I.
2. Turn the crown clockwise 20 times. Following the movement of the watch, the date and time need to be reset.
   Note:
   Do not change the date between 9 pm and 3 am during which the automatic calendar changes are in progress. Doing so could damage the automatic movement.

Setting the Time and Correction of Date
To make the rapid correction of the date, pull out the crown to position II and turn the hour hand clockwise until the correct date is displayed. Then, push the crown back to position I.

To set the time, pull out the crown to position III* and turn it until the hour and minute hands are set to the desired time. The date will change every passing of midnight. After the adjustment, push the crown back to position I.
Note:
When setting the crown in position III, the second hand will stop.

WATCH CARE TIPS

If you have a hand-wound watch, it is advisable to wind it every morning. Mechanical watches must be serviced at least every three to five years to have the mechanics checked and relubricated. The tiny parts inside the watch are under tremendous strain, so friction is their greatest enemy. Lubrication prevents the bearings from drying out and grinding away the steel parts.
Exposing your watch to high temperatures, such as placing it on the dashboard of your vehicle or submerging it in a hot tub, may cause the watch to malfunction, may shorten battery life, or may damage its internal components. Leaving the watch in extreme cold temperatures may cause irregular timekeeping. Do not expose an analogue quartz watch to magnetism. If you do, it may temporarily stop operating or may show gain or loss in time. To ensure that it maintains its water resistance, make sure the crown of
the watch is always pushed against the case. You should have your watch checked once a year for water resistance. Condensation inside your watch is an indication that its water resistance has been affected.For maximum performance, regularly wipe your watch with a clean, soft cloth. Stains, water spots and dirt that have accumulated on the case, crystal or bank may cause premature wear. If you use your water-resistant watch in the shower, chlorinated water or saltwater, rinse it with fresh water and dry it thoroughly afterwards.

Care for the Crystal Surface

•  A watch may have a scratch-resistant sapphire crystal face, but that doesn’t mean you should toss your watch on top of the dresser or into a drawer at the end of the day. It is better to store or wrap it in a soft cloth before placing it down.
•  Replace broken or scratched crystals immediately. Even a hairline crack can bring dust or moisture into the mechanism, affecting the accuracy.

Care for Metal Bracelets

•  If you participate in activities that cause you to sweat excessively, you may want to consider getting a watch with a metal bracelet or rubber strap, rather than a leather strap.
•  Since the metal bracelet is worn next to the skin, it collects dust and perspiration, which becomes soiled if not cleaned regularly. This is particularly true of the inner mesh
• Of the bracelet.
•  When soil and rust are present in a bracelet, they are dissolved by perspiration and can cause staining of the cuffs and, in some instances, irritation of the skin.
•  Wipe dirt and perspiration off with a soft, dry, lint-free cloth. If the watch is water resistant, you can occasionally clean the bracelet with a soft brush and warm soapy water. Dry the bracelet completely.
•  A toothpick can also be used to clean any dirt that has built up in the bracelet or casing of the watch.

Care for Leather Straps

•  Straps that are made of natural and genuine leather will gradually deteriorate with constant exposure to perspiration. If not cleaned, perspiration can wash out the natural oils and cause the leather to become dry. Any moisture should be blotted with a soft cloth or paper towel and the strap should be allowed to dry naturally.
•  Salt residue and soil can be removed from leather straps by cleaning it with a dampened soft cloth and mild soap (or saddle soap, which is special leather soap).
•  Wear the strap slightly loose, with an allowance of one finger space between the wrist and strap. This invites air circulation and allows any moisture to evaporate.

Care for Rubber Straps

•  Rubber straps should be washed frequently with mild soap and warm water using a soft brush.
•  Solvents, oils, perspiration, tanning lotions and salt can cause rubber to deteriorate if not removed.
