Mercari suspicions

[richhaynes]

Yesterday I saw a newer Omega aqua terra with a black leather band at an attractive price on Mercari. I have used Mercari one time in the past to buy a camera, and the transaction was smooth with no problems. What gave me pause this time is the seller has no prior transactions, and there was no detailed description of the watch. Then, as I continued to browse, I saw what looked like the identical watch for sale by two other distinct sellers, both of whom also had no prior transactions! In fact, the photos were almost the same. I wonder what exactly is going on here.
