The same advice from before:
"The case back should have engravings - both versions of the case used on this model had engravings on the case back, so if they are not there, they have been removed. BTW this is the first version of the case.
Please ask the seller to send you the full serial number, and post it here - I'll double check it to be sure this isn't some kind of franken. The fact that he sent you such good photos of the watch, but then a crappy photo of the movement, makes me feel uneasy."
Look we are willing to help you, but if you want anything other than what's been said, you need to follow up with them and get the serial number. Otherwise, you need to "shit or get off the pot" as my mother would say...
