We recommend delicately cleaning the case with a microfiber cloth to avoid scratching the case. It is also important to tighten the screw-down crown after setting the time on your watch.
Concerning rinsing your watch, it is preferable to rinse it with fresh water after swimming in chlorinated or saltwater. This allows removing the salt or the sand that could block the case or the crown.
Avoid all direct contact with chemical cleaning agents, solvents, detergents and other abrasive products, as well as cosmetics, which can damage the case, the bracelet, and the rubber joints.

Maintenance of the movement

Your watch’s movement is a high-end precision mechanism that requires to be preserved from extreme temperatures (+60°C, -0°C), from temperature shocks (like hot springs, hot showers, saunas…) and from brutal shocks (extreme sports, golf, tennis…). All damage caused by an inappropriate use of the watch will not be covered by the warranty.
The precision mechanism of Reservoir watches is particularly sophisticated, due to the fine watchmaking complications (retrograde minute, jumping hour and power reserve) that allow a unique time display. It is therefore recommended to refer to a certified service center every 3 years for a regular servicing, and every 5 to 7 years for a complete servicing.

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.


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.

Changing the bracelet

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.

Changement de bracelet

Changing the bracelet can de done very easily thanks to the quick release spring bars that come with the watch. To change the bracelet, please follow these steps:
– Position the watch upside down with the inside of the bracelet facing you.
– Find the pin on the quick-release spring bars, and with your nail, push it towards the center of the bracelet and carefully remove the straps.
– In the same way, insert the quick-release flash pumps from the fabric straps. Make sure the quick-release spring bars are well in place by delicately pulling on the straps.
