Your watch is waterproof, and as such, we strongly advise that you take it to your local jeweler or watchmaker and request that the battery be replaced. The replacement of the battery and the reassembly by a professional will ensure the watch will remain waterproof after the battery change.

Note:

For optimal use of your Withings watch, we recommend replacing the original battery with a non-rechargeable CR2430 coin cell from Toshiba, Maxell or Omnergy.
