Apple watch

Hi,

Personally my apple watch (Series 5) doesn't take any longer than 2 or 3 hours to fully charge but can depend on the model, charging voltage and if anythings going on in the background like music sync or a software update.

Apple Watch - Battery - Apple (UK)

Hope thats useful.

If it has been in an uncharged state for a very long time (e.g. months), it may take a while. Or, it may never completely charge again. One of the worst things you can do to a lithium ion battery is let it sit at 0% for long periods of time.
