It's not exactly unfair. As you can see there are many still waiting for their watches who ordered only 2 minutes after launch of the preorders. What delivery window did Apple give you when you ordered? As long as they deliver by the end of that window there's nothing to complain about.
I really don't mean to be rude and I really understand how frustrating it is to see others getting their watches earlier even when they ordered after you, but there's really nothing you can do about it. Nevertheless I hope you get charged today and receive your watch tomorrow, fingers crossed!!
