As per the email Dean posted (see below) they gave as their adress Beurstraverse 99 in Rotterdam. I went there this morning and as expected no Euro-Watches but Siebel, a low end jeweller and certainly not a buyer of vintage watches. Picture of the shop as per this morning:

Email:

Euro-watches Netherlands
Beurstraverse 99
3012 AT
Rotterdam.

We received your offer and have agreed to go ahead and purchase the watches for the price you are selling it, however in as much as we would like to buy it immediately we do not subscribe to online buying we invite seller to Rotterdam Netherlands where we have our jewelry store for a face to face deal there we will access the product firsthand and pay for it.

NB: Please be advised that we will make full refunds for sellers expenses which includes travel expenses and hotel bills, we would like to know when you plan to make the trip so we make adequate arrangements to receive you.
