Maintenance tips and advice Reservoir Watch

Water resistance

Reservoir watches are water resistant up to 5 bar/ ATM (50 meters).
Make sure the crown is well screwed down before using it underwater. Do not handle the crown underwater. The water resistance of Reservoir watches is guaranteed by security joints that can be damaged by natural wear, temperature shocks or cosmetics. If condensation appears under the sapphire crystal, the water resistance system of your watch is damaged, and it is recommended to go to a certified Reservoir service center to repair it.


You can clean the case of your watch as much as you want with a microfiber cloth. After swimming in seawater, it is recommended to rinse the case of your watch with clear water.


The movement of your watch is a high quality mechanism that requires to be preserved from extreme temperatures (+60 °, 0 ° C), from thermic chocks (ex: hot springs, hot showers, saunas, hammams…) and brutal shocks (extreme sports, tennis, golf…). All damages resulting form an inappropriate use of the watch will not be covered by the warranty.


Magnetic fields are produced by many different sources, such as mobile phones, computers, refrigerators and other electronic instruments. These magnetic fields can suddenly alter the precision of your watch. In that case, you should refer to an authorized RESERVOIR service center, where a specialist will examine your watch and demagnetize it if necessary.


Bronze is a mixture of metals that includes copper. Bronze naturally oxidizes. Thus, your bronze watch will naturally gain a patina over time, giving it a unique and original aspect. However, we recommend avoiding any contact between your bronze watch and abrasive products.


On some of our models, the 316L steel of the case and/or of the butterfly folding clasps is coated with PVD (physical vapor deposition). This is a surface treatment method used in the horology industry to achieve tinted metallic coatings with a high resistance. PVD being a coating material, it is possible that the stainless steel under the PVD arises in case of shocks, deep scratches or regular friction. The warranty does not cover such cases, inherent to all coating materials.

Leather straps

The leather straps require a close care in order to preserve their beauty and suppleness. Delicately rub the leather straps with a soft cloth or a microfiber cloth before putting your watch away in its case. We also advise you to protect the straps from an immersion in water, and from sweat, humidity, acid solutions or other harmful products.
