Not sure why you're struggling with this
@Georgewg, when the answer seems so obvious to most everyone who's commented. Return any/all "hazy" examples ASAP, full stop. Honestly I think the seller you bought from is doing you a HUGE solid by even allowing you to return the one you already wore for a few days... Thank them profusely for allowing the return, send the watches back, and be done with this boondoggle.
Others with this problem have often noted that it gets worse with time. And you bought THREE of the same model? Maybe you actually planned to keep and wear all three, but seems more than likely to me that
just maybe you planned to flip two, make a few bucks, and keep one at a reduced price. If that assumption is correct, are YOU going to feel alright selling "hazy" examples of this watch to somebody else? Don't you think they'll end up returning the "hazy" watches TO YOU? Likely in "less than perfectly new" condition, as you are going to do to this seller after having worn one for a few days already?
