Re: My Watch went blank with a twirling sign in the center.
Maybe you can identify what the twirling sign is telling you:
eg: Could it be the red or green charging "lightning bolt".
Status icons and symbols on Apple Watch
Wondering if the watch actually charged ok:
or
perhaps the watch is caught up while performing an action that it can not complete: eg: pairing
You could try re-starting the Watch:
