How can I update my Apple Watch s3

Apple Watch series 3 can be a bit difficult to upgrade, but here to help.

If you haven't tried the update yet please check this link: Update your Apple Watch - Apple Support

and follow the steps provided.

If you have tried the update, but it fails because of lack of space on the series 3:

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

The space problem is the most common issue with updating the series 3 so I hope this would work.

The apple watch 3 GPS only has only 8GB of internal storage, most of that is taken

up by the operating system and other critical software with not much space left for the

update.So installing or even pairing to an ios15 phone is proving nearly

impossible for just about all the watch 3 users on this forum.

same applies to Apple watch 1 and 2 they are almost impossible to either pair or

update with an ios 14 or ios15 phone.

Your best course of action is to call in at an apple store and ask them to pair/update it for you.
