Not enough space to update my Apple Watch

Unpair your Apple Watch via the Watch app on your iPhone.

Then Re-pair your Apple Watch again,this usually frees up

enough storage space to update your watch.And without any loss of data.

Or this;

If you don’t have enough space to update your Apple Watch – Apple Support

That’s generally understood to not be working on Series 3 watches.

I, like many others, (after resetting my watch, installing no applications, then wiping all data from mail, photos, podcasts, contacts, and every other baseline app), can go to Usage and still see 1.7GB of storage used, but almost no data to n the listed apps. Rebooting does not help.

Sounds like he, and I, have already done that. Still says not enough space even with making sure to install no music, no apps, nothing. Have spent hours trying to update to the point I will probably not repair watch and be done with using an Apple Watch. It’s nice to have… but not worth my trouble

That process is not working.

Same here!

its very sad that Apple developers are getting bad at their jobs. They should have checked to make sure the new update file size is enough for all models.

Yea, doesn't work, and takes what seems like forever, just to tell me not enough space.

I’ve done the same. No response from Apple?
