If you have not worn your automatic or manually-wound watch for a while, wind it up fully by
turning the crown twenty times. 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. Take care not to force the crown once you feel resistance.
Do not change the hour or date between 10 p.m. and 2 a.m. It is during this period that the date changes, and it may cause a damage of the movement.
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 the case of a shock to the watch, consult a Montblanc boutique or certified Montblanc retailer. Even if no scratches or dents are visible, its movement may have become damaged. Do not wear other jewellery on the same arm 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, calf, 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, thus causing 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 these, clean it with lukewarm water and a toothbrush. After, rinse it with fresh water and use a soft cloth to dry it or leave it to dry naturally. Never use a heating device. Lastly, please be sure to check the stones regularly to ensure they are still securely set.
