Fenix 7x Sapphire Solar just arrived - Dead after 1 hour

Sorry for the rant .. i am just frustrated. I managed to get this watch very early. 
During the setup, i was fiddeling with the watch faces, the START Button stopped working, there was a noise while pressing it, and now it does not click anymore and has no function at all. 

I called Garmin to get a replacement, they where very friendly and helpful but told me that this might take a while, as there is no stock currently ... 
So i will return it to the dealer ( i bought it somewhere else ) 

Otherwise the watch does make a good impression...
