if you had requested qc pics you could have avoided this situation. now you've learned a lesson, perhaps?
if i were you i would open it up, remove the movement/dial, wipe off oj's blood, slap it back together and wear it. if you aren't comfortable doing that you have a few options:
1. sell it in m2m, take the money and buy another;
2. send it to a forum modder, have it water proofed, relumed, whatever and have the blood removed at that time, 2 birds one stone and all that;
3. wear it as is, knowing no one will ever see it while it's on your wrist.
i would not however send it back. it will cost more than is worth it to send it back to china, cause unnecessary trouble for the td and waste both your time and his.
bottom line next time request qc pics.
or buy from member sales, that's what i do.
