Battery replacement: Batteries should be replaced at an Authorized Wenger retailer or service center. Do not try to change the battery yourself. It is important to have your watch serviced by an Authorized service center to preserve the warranty and to carry out a water-resistance test. Taking your watch to an unauthorized retailer will invalidate the warranty.

Battery end-of-life indicator: On selected models, the battery end-of-life (EOL) indicator signals that the battery should be replaced. In this instance, the second hand does not move for 4 seconds then jumps to the correct time. For digital displays, the indicator will blink which means the battery needs replacing. The EOL indicator lasts for approximately one week, then the watch will stop.

Battery life: Our quartz watches are battery operated. The battery life is approximately 24 months from the time of assembly or last service. The battery life depends on a number of factors. For instance, a chronograph consumes more energy than a 3-hand timepiece.

Water resistance Classification:
Watches are classified by their degree of water resistance. Check the water resistance information on the case back of your Wenger watch and refer to the water-resistance table below :

Water-resistance chart
Meters	Feet	ATM	Usage
50	165	5	Suitable for showering or swimming in shallow water
100	330	10	Suitable for swimming or snorkeling
200	660	20	Suitable for scuba diving
500	1650	50	Suitable for serious deep water diving

Water-resistance guarantee: The water-resistance of your watch cannot be guaranteed indefinitely. The gaskets may age, crowns or pushers may receive knocks and changes in temperature may weaken the water resistance. We recommend a water-resistance test every 18 months at an Authorized Wenger service center or at least every time the case of the watch is opened.

Important: Do not operate the pushers or the crown while your watch is underwater. Make sure that both are properly pushed back or locked into place.

Cleaning: To preserve the attractive appearance of the watch, clean the case and the strap  regularly in slightly soapy water, then rinse in clean water and dry with a soft cloth.

Soft toothbrush: You can also use a toothbrush to clean your watch. Make sure you choose a brush with soft bristles to avoid scratching the watch case or strap.

Leather strap: To clean your leather strap, first rinse it under clean water then rub it with a soft brush and a little soap. Wipe with a soft cloth and leave it to dry. Keep newly cleaned leather away from any source of heat

Authentic Wenger leather straps will last an average of 12 to 18 months, under normal conditions of use. This lifespan depends on various factors such as skin acidity, perspiration, contact with chemicals, weather conditions, climate and humidity. For instance, contact with water or any other liquid may cause the strap to wear prematurely.

To keep your leather strap in a good condition we recommend you remove your watch for daily showering or swimming.

If you have a very active lifestyle, particularly involving frequent exposure to salt water and heavy perspiration, we recommend a steel bracelet or rubber strap.

The color and suppleness of leather straps are subject to change with time and exposure to external elements.

Dry place: Keep your watch in a safe, dry place. To prevent any damage we advise you to store the watch in your Wenger box or in a soft pouch.

Accuracy: Allow the movement to work for a few days to re-establish its original accuracy.

Luminescence: The dials and hands of Wenger watches are treated with Super-Luminova.  Your watch must be exposed to bright light in (daylight / artificial light) for the markers and hands to remain luminescent in low light conditions.

Do not expose to chemicals, solvents or gases as they can cause deterioration, discoloration and damage to the case.

Do not apply any cosmetics or perfumes directly onto the case, leather strap or metal bracelet.

Avoid high temperatures and strong magnetic fields.

Before your vacation: To prevent any infiltration from water or dust, you should make sure that your watch has passed a water-resistance test during the last 18 months at an authorized Wenger service center.

At the airport: To protect your watch from magnetism, we advise you to remove your watch before going through security control.

Before showering / swimming etc.:

• Check that the crown is fully pushed in or locked down against the case in order to preserve water-resistance.
• To protect your leather strap from deformation or discoloration avoid contact with water.
• For frequent or prolonged use in water, we recommend a steel bracelet or rubber strap.

After each exposure to salt water, rinse the watch carefully in fresh water and then dry it.

Condensation: A sudden change in temperature may cause condensation to appear under the crystal. This does not affect the watch’s functions and will soon disappear on its own. Nevertheless, it indicates a water-resistance weakness, and we recommend that you consult an Authorized Wenger  Watch service center.

Warm conditions:

• Temperatures above 60°C (140°F) can have a significant effect on the mechanism and battery life.
• High temperatures cause discoloration and can shorten the lifespan of the leather strap. We do not recommend that you expose your watch to extreme climate conditions.
• Intense light: This can age materials used in your Wenger  watch, such as coatings, plastics, rubber and leather.

Cold conditions:

• In cold environments, we recommend keeping your watch on your wrist so that it remains close to body temperature.
• Below 0°C (32°F), the mechanism oil can lose fluidity and slow down the movement.
