Mechanical movements are composed of hundreds of parts that are assembled with infinite precision and care. To reduce friction, spare parts are lubricated with oils and grease. Over time, oils can thicken and greases can dry, affecting the performance of the movement of the watch. If you have not done your watch for five years or you have not worn for a long time, it is recommended to complete the full service.

This service does not include:

Polishing. This is an additional service.

Replacing additional parts, such as dial, telescope, crown or needles, which is charged separately.

Even if you take good care of your watch, scratches or spots may appear on the housing or bracelet. Montblanc recommends that you polish your watch from time to time so that it finds its brilliance and original shine. For this, the watch must be fully dismantled, separating the bracelet from the watch to polish each element individually. It is not possible to polish the glass according to this process as it would eliminate the anti-reflections protection. In addition, engraved or satin surfaces would be damaged by the brush.

Your watch can not be polished more than seven times. Some scratches can be too deep to be eliminated. It is not possible to polish the parts that have undergone special treatment (PVD, ADLC, etc.) or certain materials (ceramic, brass, tantalus, etc.).

Please note that polishing is not an independent service, but an additional option proposed only as part of a maintenance service or complete service to ensure the tightness of the watch.

This service includes the operations below:

1. Complete disassembly of the watch

2. Polishing using different brushes and polishing pasta:

- Application of an abrasive paste with a hard brush to eliminate surface stripes

- application of a hard paste with a brush to smooth the upper surface

- application of a fine paste with a flexible brush to restore the brilliance and shine of the room

3. Ultrasonic bath cleaning

4. Closing the watch box

5. Final control (aesthetic)
