My Apple Watch Series 3 is not updating to 7.3.3 because of space lower than 3.1 GB

An update came last month to install OS 7.3.3 on my watch and I tried to install, it needs 3.1 GB disk space which is not available. After so many retries it didn't work and I had to unpair. It didn't work even then.

After that I factory reset my watch, now when I am pairing it first ask to update to 6.5 and when i do it goes to update for 7.3.3 and again stucks on low disk space. Any solution please?

Apple Watch Series 3, watchOS 6

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;

I have the same. I am stuck in a loop of unpair, pair then update. I can’t do anything on the watch app on my phone except pair, unpair or update but when I update (after unpairing then pairing) it says I don’t have enough storage for the update and to get on my watch app on my phone. Which only allows me to pair unpair or update. I have an Apple Watch 3 and an iPhone 12.

I am following. I have a useless Apple Watch 3 right now. So frustrating! I have unpaired and reset watch. I was finally able to download update and now phone says “installing”. I have my watch on charger near my phone but I will need to use my phone today when I get on the road. Does phone have to stay near watch until done?
