Apple logo white then turns orange

Orange or red usually means some kind of problem - anything from very low battery just needing to be charged, through to major battery problems. Please see Apple's suggestions in

Check your battery and charge your Apple Watch - Apple Support

If your Apple Watch won't charge or it won't turn on - Apple Support

Also be aware the display while charging may go to blank screen. This is normal behavior, gently tap or move the watch to activate the display for a few moments.

This happened same with me, and I went to the Apple store to fix it, they are saying it there is a hardware issue affecting the normal function of the ethernet port, and Apple is charging me CAD 389 Plus TAX to fix it

I also encountered a similar situation as you. How did you handle this? What about your current Apple Watch?
