If you have not worn your automatic or manually wound watch for a prolonged period of time, wind it fully by turning the crown twenty times. Further details are specified in the respective Service Guide.

In order to ensure the performance of your manually wound mechanical watch, we advise you to wind the crown once a day, preferably at the same time. Be careful not to force the crown once you feel resistance.

Do not change the hour or date between 10 p.m. and 2 a.m., the period during which the date changes, as this may result in damage to the movement. Please refer to the service guide for further details.
Do not expose your watch to temperatures higher than 60° Celsius (140° Fahrenheit) or lower than –10° Celsius (14° Fahrenheit). As your body and clothing will warm up the watch, its actual temperature will be different to the ambient temperature of your environment.

In case of a shock to the watch, consult a Montblanc boutique or certified Montblanc retailer. Even if no scratches or dents are visible, the movement may be damaged.

Do not wear other jewellery on the same wrist as your watch in order to preserve the patina of its surface and the integrity of the material. To preserve the pristine condition of your alligator, calfskin, satin or rubber strap, avoid contact with humidity, salty water, soap and cosmetic products. Do not treat your strap with wax, leather or shoe polish, as chemicals may damage the leather, lining or stitching. This may cause the strap to lose its original shine. Avoid prolonged exposure to high temperatures and direct sunlight to prevent the colour from fading. Please note that strong perspiration may darken the leather. Diamonds, set on a bezel or crown, must be handled with care to maintain the lifetime of their brilliance. Avoid contact with chemical products such as fragrances and detergents, as these substances will tarnish precious stones. If your watch has been exposed to such products, clean it with lukewarm water and a soft toothbrush. Then, rinse it with fresh water and use a soft cloth to dry it or let it dry naturally. Never expose it to a direct heat source. Additionally, please be sure to check the stones regularly to ensure they are still securely set.

We recommend to keep your Montblanc watch in the box in which it was received. When travelling, we advise you to keep your Montblanc watch in a specially designed travel pouch to protect it against shocks and damages.
When not using your Montblanc quartz watch for a very long period of time, please visit a Montblanc boutique. They will prepare the watch for the duration of storage. 

We highly recommend testing the water-resistance of your watch at least once every three years. Water inside the case may result in condensation, which can lead to deterioration of the movement. If you often engage in sports or are in frequent contact with water, the test is required once a year. Even though Montblanc watches are tested under various conditions, we strongly advise you not to pull out the crown or use the pushers while swimming, cleaning the watch or when the watch is submerged under water.
After swimming in the sea or in a swimming pool, clean your watch and stainless steel bracelet with lukewarm water and rinse it. Then, use a soft cloth to dry it or simply let it dry naturally. Never expose it to heat sources, such as hairdryers or radiators. If the watch has a leather strap, avoid any contact with water.
Also avoid any contact with chemical products such as solvents, cosmetics or detergents. They may damage the case and the bracelet or cause the gaskets to deteriorate.  

Magnetic fields, such as those produced by TV sets, radios and magnets, occur everywhere. They affect different parts of a watch’s movement and change its performance. You can use a compass to check for magnetic fields. If the needle responds, then you are in a region of magnetic influence.
Please note that this only concerns mechanical movements. Quartz movements may lose a few seconds, but will return to normal once you leave the magnetic field.  

A stainless steel bracelet will last much longer if it is adjusted to fit your wrist perfectly. The bracelet on your watch is subject to wear and tear and needs to be maintained. Even if you follow the care procedure described in your service guide, parts of your bracelet may begin to wear out with time (clasp, links, pin, etc.).

This service includes the following operations:

1. Dismantling of bracelet
2. Replacement of defective accessories or parts
3. Addition or removal of extra links (size adjustment)
4. Cleaning of bracelet with ultrasonic bath to remove dust or dirt between the links
5. Final check (aesthetics).

This service does not include:

• Additional parts such as links or clasps. These must be paid for separately.
• Polishing. This is an additional service. The polishing service is only offered together with a complete service. There are no services available for cleaning or maintaining leather straps. If your strap has worn out, we invite you to visit one of our Montblanc boutiques to take a look at our fine selection of straps.

Montblanc highly recommends having your watch’s battery changed on a regular basis.

A weak battery may result in your watch being slow or even in damage to the movement due to battery leakage. We advise you to never use an old battery and to bring your watch to a Montblanc boutique or certified Montblanc retailer to ensure it is handled by a qualified technician. During the battery service, the back is removed. Both the battery and the back gasket are replaced. Screws are only changed if necessary.

Montblanc does not recommend simply changing the battery and back gasket alone. Rather, it is recommended to request a maintenance service at the same time to reduce the risk of water entry due to worn out gaskets, which may cause damage to the movement and internal parts (hands, dial, etc.).

If this were to happen, a complete service would be required, thereby costing far more than the recommended maintenance service.

1. Dismantling of accessories
2. Replacement of battery and back gasket
3. Cleaning of case or case and bracelet with soft cloth
4. Performance test
5. Function testing
6. Watch head closing
7. Water-resistance test
8. Final check (aesthetics).

It is very important to request a maintenance service for your quartz watch every three years. This maintenance is essential to ensure the utmost performance of the movement.

During the maintenance service, all parts of your watch are dismantled, except for the movement, dial, hands and battery. At the same time all gaskets are replaced.

Back screws are only replaced if necessary.

This service includes the following operations:

1. Complete dismantling of the watch
2. Inspection of all parts
3. Cleaning of case or case and bracelet with ultrasonic bath
4. Replacement of battery and gaskets
5. Performance test
6. Function testing
7. Watch head closing
8. Water-resistance test
9. Final check (aesthetics).

Your watch is composed of a mechanical system that may lose precision over time and of gaskets with a limited lifespan. In order to guarantee the water-resistance and the performance of the watch’s movement, it is essential to have your watch serviced regularly:

Every three years for an automatic/manually wound watch
Every year for COSC* watches (to ensure precision)
 

*COSC: Contrôle Officiel Suisse des Chronomètres (Official Control for Swiss Chronometers). This firm, independent of Montblanc, certifies high-precision movements. For more details, see www.cosc.ch.

This service includes the following operations:

1. Complete dismantling of the watch
2. Inspection of all parts
3. Cleaning of case or case and bracelet with ultrasonic bath
4. Replacement of gaskets
5. Performance test (precision, amplitude)
6. Function testing
7. Watch head closing
8. Water-resistance test
9. Final check (aesthetics)

Both services do not include:

• Polishing. This is an additional service.
• The replacement of additional components such as the bezel or crown must be paid for separately. If the dial or hands have to be replaced, Montblanc recommends a complete service, as disassembling the dial and hands means direct contact with the movement.

Mechanical movements are made up of hundreds of different parts assembled together with painstaking attention to detail. To reduce friction, interacting elements are coated with different types of oil and grease. With time, the oil between components may thicken and the grease may dry out, reducing the performance of the watch’s movement. If you have not serviced your watch in the last five years or have not worn it for a prolonged period of time, it is recommended that you request this service.

This service includes the following operations:

1. Complete dismantling of the watch
2. Inspection of all parts
3. Complete revision of the movement
4. Polishing of the case or case and bracelet
5. Exchange of all gaskets
6. Performance test (precision, amplitude)
7. Function testing
8. Watch head closing
9. Water-resistance test
10. Final check (aesthetics)

This service does not include: The replacement of additional components such as the dial, bezel, crown or hands must be paid for separately.

Even if you take good care of your watch, scratches or blemishes may still appear on the case or bracelet. Montblanc recommends polishing your watch from time to time to recover its original brilliance and shine. To do this, the watch must be dismantled completely, separating the bracelet from the watch itself to polish each part individually. It is not possible to polish the glass in the same way, as the anti-reflection treatment would be removed. Moreover, other surfaces such as engraved or sandblasted finishes would be harmed by the brush.

Your watch can only be polished a maximum of seven times. Some scratches may be too intense to be removed. It is also not possible to polish treated pieces (PVD, ADLC, etc.) and certain materials (such as ceramic, brass, tantalum, etc.).

Please note that polishing is not a separate service, but an additional option that is only offered together with another service, either maintenance or complete, to guarantee the water-resistance of your watch.
This service includes the following operations:

1. Complete dismantling of the watch
2. Polishing with different brushes and polishing pastes

• Abrasive paste with a hard brush to eliminate superficial scratches
• Hard paste with brush to smooth the uppermost surface
• Fine paste with soft brush to restore the shine and brilliance of the piece

        3. Cleaning with ultrasonic bath
        4. Watch head closing
        5. Final check (aesthetics).
