Hi dear all, I am new to this forum and I found out that there are a lot of experts here so I would like to ask for some advice. I am now hunting for my first constellation, preferably stainless steel one and I have made some of the reading regarding constellation counterfeits, redials, movement...but the value range for one is kind of confusing. I came across this connie on ebay: http://www.ebay.com/itm/371209950068?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT The dial looks legit but the owner could not provide the photos of movement and case back. He claimed the authenthicity and said that he bought this watch as a second hand from an authorised omega dealer (not so sure if a real authorised omega dealer would be selling second hand watch in the store). And is the crown an improper one? I read somewhere in this forum someone was saying that some of the crown like this were actually replaced by omega themselves. Would like to know if it is worth the gamble to buy, and if it is worth, how much is the appropriate price to pay for? Thanks!
