Apple watch malfunction

The watch vibrates and the screen spasmodically moves up and down without end - like it is having a seizure. I've tried restarting/resetting/restoring to no avail. I think it must be a hardware issue. Anyone esle have this problem? Is there any hope? I've had the watch just over two years so the warranty is expired and I'm not sure its worth the money to fix it.

Thanks,
