As stated on the back of the case, all Montblanc watches are water resistant to 30 m; the Sports Collection is water resistant to 200 m. After contact with salt water, it is recommended to clean the case carefully using freshwater and a soft cloth. Watches should be tested for water resistance every two years, or when the battery is changed, by an authorised Montblanc Service Center.
