In my quest for a Rolex Submariner 168000 I have stumbled across an Italian store called della Rocca Gioielli http://www.dellaroccagioielli.it). They seem to offer an almost endless assortment of vintage watches, the prices are decent and the store seems reliable. They have posted regularly on their twitter and facebook accounts for several years, they have a bilingual customer service, all corporate information on the webpage footer. I can't find any mentionings anywhere of them being a scam.
It is almost as it is too good to be true so I did some research, and here is where it gets fishy: I can't find any customer references or comments about this store in any other language than Italian. Nor does the certification they offer from "CHS SA GENEVE" seem to ever be referenced to in any independent sources and in the "how to order" section they mention accepting credit card payments "through a secure server of KEY CLIENT.", which I can't find any english speaking sources for.
All in all I am very perplexed. If this is a scam, somebody has put a ridiculous amount of time into it. If not, how come nobody outside of Europe have acknowledge what seems to be a very good source for vintage watches?
