After trying a factory reset it seems dead


Hello everybody,
I have the first kind of pebble watch. After some display deterioration I decided to do a factory reset. Never got past the screen with a cloud at the top and several app holding rectangles below it. Tried unsuccessfully to pair to my Iphone, tried to uninstal and re-install the pebble app from App Store. No chance to move from there. Now that diplay with the cloud does not show up any more.
Does anybody has a suggestion on how to recover ?

Thanks in advance,
