Well after a dozen restarts of the watch and the phone I finally got the watch to decide to download OS3. Turned off Bluetooth of every device nearby, deleted wear OS and at last I'm up and running.
I've bought the premium watchmaker option so now I'm trying to work out how to join a community to download some new watchfaces. Just hope that doesn't prove as difficult.
Many thanks to Tognola Lucy.

Happy I could help you. Didn't get that you're on iOS. As far as I read here E4 has quite a lot of issues with iOS and the worst part that TH seems to literally have stopped the support for E4😖

I bit the bullet and picked up an E4 45 😊 I feel I need a replacement battery though 😱 it lasts maybe 5 hours (not done any battery saving adjustments yet and have been “playing” a little 😏). It had sat in its box for approx 6 months prior to me buying it but previous owner said it did last all day prior to storing it. Is there a replacement available these? Should I go to Tag or replace it myself?
Thank you 🙏

I think TAG Heuer had announced back then that one could ask for a battery replacement. But whether they still offer it and whether it is available everywhere, I have no idea.
However the battery on my E4 45 lasts easily 24 hours or more and I've had it for over three years now. Wait a little. In the beginning the watch downloads in the background a lot of updates and you tend to play around and try more than you will be on a day to day basis, once the novelty wears off.
