Recycle It Responsibly if it’s Already Too Old 

Some Apple Watch models are simply past the point where reusing them makes much sense. Maybe the battery is rough, the model is too old, or the device just doesn’t fit into your life anymore. In that case, responsible recycling is a much better outcome than letting it sit in a drawer forever or tossing it out the wrong way.

This is the least exciting ending, but it’s still a good one. If the Apple Watch no longer has practical value, recycling it properly is a better solution than pretending you might use it someday and never touching it again.

Before you do that, though, just remember to unpair and erase it, so your data is still safe. When all of that’s done, you can take it to Apple so they can start the recycling process for you.
