Maintenance tips

Regular maintenance

A watch is one of the few devices that operate continuously around the clock. To ensure optimal reliability and long-life, an authorized Baume & Mercier After-Sales Service Centre should carry out a complete watch service every 3 to 5 years.

Battery change

The average life span of your battery is 2 to 3 years. We advise you to never leave a worn battery inside your watch, because there is a risk of its deterioration damaging the movement. We recommend you have your battery changed by an authorized After-Sales Service Centre.

Water-resistance

All Baume & Mercier watches are water-resistant to a depth of 30 metres at least. For greater levels of water-resistance (50m and more),the corresponding figure is engraved on the case back.
The water-resistance of a watch protects the movement from dust, moisture and from any deterioration when fully immersed in water. The gaskets keep the watch water-resistant.
However, as they are constantly exposed to several forms of outside aggressions (cosmetics, perspiration, temperature changes), the water-resistance of a watch may decrease with time. Therefore, we advise you to have the water-resistance of your watch checked every 12 months.

! Important : Do not adjust the position of the crown or press on the push buttons to change the time, date or any other functions when the watch is immersed in water, as water may seep into the case.

If condensation appears in your watch, you should take it to an authorised Baume & Mercier reseller or After-Sales Service Centre as this may indicate a water-resistance problem.
After swimming in the sea or chlorinated water (swimming pool), carefully rinse your watch in fresh water.

Daily care

To preserve the looks of your watch and its metal bracelet, if need be we recommend gently cleaning it with a soft brush (e.g. toothbrush), dipped in slightly soapy lukewarm water. After this operation, carefully rinse your watch in fresh water and wipe with a soft cloth. This must be done each time you go sea bathing.
We advise you clean the metal bracelet of your watch every two months if you wear your watch everyday. Before any cleaning, ensure the crown of your watch is correctly in place (pushed in or screwed in depending on the model). Adjusting your watch close to the wrist will minimise the effects of wear and tear of its metal bracelet.

Changing the leather and rubber strap

We recommend entrusting the changing of the leather or rubber strap to an after-sales service centre authorised by Baume & Mercier. We will use straps that perfectly hug the shapes of the case, which give the final touch to the quality of Baume & Mercier watches.

Magnetic fields

Our environment is increasingly subject to disturbances due to magnetic sources. These disturbances can have an effect on the working of your watch whether mechanical or quartz.

A quartz watch can be affected when it enters a strong magnetic field, however it works normally again when no longer in it. This disturbance therefore lasts as long as your watch is at the heart of the magnetic field.

A mechanical watch is also sensitive to strong magnetic fields. The resulting disturbance could, in some cases, magnetise steel parts in the movement and more particularly the main spring. Some parts are likely to adhere to one another and the watch could advance considerably or stop. In this case an after-sales service centre authorised by Baume & Mercier must undertake a demagnetisation intervention.

Knocks

Whether thermal or physical, avoid knocks!

Chemical products

Avoid any direct contact with solvents, detergents, perfumes and cosmetic products that could damage the bracelet, case or gaskets.

Temperature

Avoid extreme temperatures above 60 degrees C (140 degrees F) or below 0 degree C (32 degrees F), as well as brutal temperature changes.
