Hi I just bought from eBay two Omega bracelets with the ref no 1181/215 and I suspect that are fake because I already have two watches with the same ref. no on the bracelet and are some differences. I'm not sure because there are also differences to the ones that I already had. So the differences to the ones which I already have are: 1. On the clasp the logo Omega it's embossed different. 2. The end link it's a little different. But the differences with the bracelets bought on eBay are greater ... 1. The interior of the clasp it' not stamped very crispy.. 2. The links are solid 3. The links are wider.. In my mind if a bracelet has a reference number it doesn't matter it was produced at 10 years difference it should look the same..so please help me to be sure if it's a fake and to return them. The seller sold them as NOS.Here are the pictures with the one of the bracelet bought on ebay : Here are the pictures with the ones I already had: Thank you.
