Urgent: What you think of this Tudor Sub?

[kooltzar]

Here is a Tudor sub for sale on ebay, auction expiring in about an hour:

http://www.ebay.ch/itm/Tudor-Oyster-...#ht_500wt_1128

I have asked the seller questions about the engraved serials, pictures of those, whether all the parts to the watch are original and about accuracy. He answered just an hour ago after several reminders that "he thinks its all original" and that the watch works accurately, but no other answeres, especially full refusal of answer re. engraved numbers and no pictures. This behaviour made me very suspicious.

Anybody know the seller? What do you think about the watch based on what you see on the pictures?
