Make sure to keep your Montblanc Summit smartwatch, charger and accessories clean. For cleaning:

- Turn the watch off and unplug the charger from the power supply.

- Remove the strap.

- Wipe with a lint-free and non-abrasive cloth. Do not apply force or excessive pressure.

- Do not use chemicals or detergents for cleaning.

All Montblanc Summit generations are water resistant*.

Montblanc Summit 2+ is rated IPx8 water-resistant. This means the watch can withstand sweat or rain and can be worn while washing your hands. However, it is not suitable for submersion in the water (e.g., under the shower, when swimming or doing other water activities), as pressurized water could enter and damage the watch.

Montblanc Summit 2, Lite and 3 have been certified as water resistant according to 5ATM. They are suitable for low-velocity and shallow-water activities like swimming in a pool or ocean. However, please avoid any high-velocity activities like scuba diving or high-speed water sports, as pressure peaks over 5 ATM could damage the watch.

Water resistance may diminish over time. Equally, dropping the Montblanc Summit, or exposing it to high pressure (e.g., water-skiing, diving, surfing, motorized water sports), temperature or humidity (e.g., sauna or steam rooms, Jacuzzis), and liquids other than freshwater (e.g. soapy water, detergent, lotions, perfumes, oil, sunscreen) can affect the watch’s water resistance and should therefore be avoided. Also, avoid pressing buttons while the watch is submerged in water.

After contact with sea or pool water or any liquids mentioned above, the Montblanc Summit should be cleansed with freshwater and dried with a lint-free cloth.

While all Montblanc Summit rubber, metal, and nylon straps are water resistant and can thus be safely used in the water, exposing leather straps to water should be avoided. The Montblanc Summit charger and other accessories are not water resistant and must be kept away from water, humidity or any other liquids. Water damages are not covered under warranty.

* Please note, that being water resistant does not equal being waterproof.

Your Montblanc Summit runs on a rechargeable lithium-ion battery that ensures it delivers the performance as promised. These batteries are considered consumables and have a limited lifespan as they chemically age. Thus, overtime their ability to store battery power and ultimately their performance, or maximum capacity, declines.

To maximize the battery lifespan, keep your Montblanc Summit at charged to at least 50% when it is not in use over an extended period of time and avoid direct exposure to hot enviroments, e.g. direct sunlight, for long periods.
