I would just do some searches in various forums. Sorry to say, If you had done that, you would know that a Crucifixion awaited you upon asking that basic question. Keep in mind, for active members, those type of questions are asked at least 72 times per week. Gets a bit frustrating!
For my self, I am first looking to make sure it is the same watch I ordered. Sometime a switch in manufacturer may occur. Then I’m looking for any major flaws, misalignments, errors deviating further from the expected flaws (based on research here on the forums) and comparison to the images shown on the TD web site.
The typical questions here on the forums regarding the QC imagery many times comes down to the angle of the photographs, take that into consideration when evaluating misalignments.
The pube comment is a true one, it happens. Check the threads.
I can go on, but my comments should give you an idea, and you should just start using that search function and rummaging around the forum threads. You will get a wealth of information.
Best of luck.????
