Cleaning
Please regularly rinse your watch in clean, fresh water to remove any sediment or other material that may accumulate on the watch during use. This is especially important after each immersion in salt water. Avoid direct contact with solvents, detergents, perfumes, cosmetic products etc., since they may damage the bracelet, the case or the gaskets.

Crystals
Mondaine watches are made with heat tempered mineral or sapphire glass crystals, depending on the specific model. Sapphire glass crystals are highly scratch resistant. A cracked, chipped, or loose crystal should be replaced immediately, as it may lead to water resistance or fogging issues.

Water Resistant
Before timepieces leave our Swiss factory, they passed water resistance tests based on international standards to the pressure indicated on the back of your watch. Water resistance, however, cannot be permanently guaranteed, as it can be affected by such things as a physical shock to the watch’s components, ageing – namely, but not limited to its gaskets – or by thermal (temperature) shocks. Extreme changes in temperature (sauna, hot tub, sunbathing, etc.), followed by exposure to cold temperatures, or exposure to certain cleansers (after shave lotion, sun cream, etc.) may cause the gaskets to expand/contract or dry out prematurely, compromising the water resistance or causing moisture beneath the crystal. These issues are not covered by the warranty and are subject to repair charges; in such instances you should send your watch to an authorized Mondaine service center for inspection and/or repair.

We recommend that all gaskets be inspected and replaced every 18-24 months by an authorized Mondaine's service center (yearly if the watch is frequently used in chlorinated swimming pools or saltwater environments). Before and during any contact with water, the crown must always be firmly pushed (or screwed-in, depending on the model) towards the case and neither the crown nor the push buttons can be activated in the presence of water.

Battery
Mondaine's quartz watches are equipped with high quality batteries at our Swiss factory. At the end of the battery’s life, battery replacement should be performed by an authorized Mondaine's service center, which will also check the full functioning and water resistance of your watch and change its gaskets, if necessary. The batteries will be collected and properly disposed of.

Power Reserve
The functioning of a self-winding mechanical Mondaine movement depends on the wrist movements of the wearer. When fully wound, the watch will have a power reserve corresponding to the model's specifications.

Crowns (applicable models)
Screw it in carefully to ensure that no water enters the mechanism.

The way you wear your strap or bracelet and how you take care of it influences its appearance and longevity. The following section will provide you with information about our different bracelet types and recommendations on how to preserve their beauty and functionality over time.

Straps
The longevity of straps depends on your wearing habits and the exposure to water, sweat, sun, and chemicals such as sun cream, lotions, etc. It is normal for a leather strap to darken and deteriorate over time. We recommend that you regularly change your strap, also for hygienic reasons. Original Mondaine straps are available at authorized retailers and online stores.
