How long can I leave my Apple Watch on a charger?

Hi

Apple advises that you can charge Apple Watch whenever you want. The battery on Apple Watch cannot be overcharged (there is also no need to let the battery discharge to any particular level first, nor any benefit to be gained from doing so):

Apple's tips for maximising battery life and battery lifespan on Apple Watch are detailed here:

Charging will stop automatically when the battery is fully charged and start again if and when required due to ongoing battery usage.

Be sure to follow Apple's safety and handling instructions (see the links below) and also note that:

• It is not possible to turn your Apple Watch off whilst it is on the charger and connected to power - this is normal.
• It is also normal for your Apple Watch, power adapter and charging cable to become warm when connected to power.

You may also find (the optional) Nightstand / Bedside mode useful:

I own an Apple Watch Series 2 which I do not wear every day. I would like to leave it on a charger so that the watch is charged and ready for use when I decide to wear it. If I leave the it on a charger for multiple days at a time could I cause damage to the watch? I may wear it once or twice a week with it on the charger the remaining time.

Thanks.

Technically, you could leave it on the charger indefinitely, since the device only accepts a charge when needed, but why leave it on that long?

Hi

Watch will stop charging when battery is full no damage will be done.
