"Apple watch wil try to install this update later tonight" iPhone iWatch shows me software ipdaye watch

"Apple watch wil try to install this update later tonight" (sic)

is now "affiched" on my iPhone and iWatch for several weeks now ...

showing 588 MB to be "unloaded" - but nothing happens (;-O)

I have done all the right things as instructed by Apple and by some "experts"

c.q. on charger @100% and WiFi coupled - eventually even Bluetooth uncoupled ...

to no avail !

I suppose that 7.5 isn't really necessary ...

although the "red dots" on both instruments are beginning to enervate !!!
