I ordered a vintage Omega watch and I am happy with my purchase. Communication was nice and helpful, package was shipped the closest working day and came on time - shipment was for free also.The watch is in a great condition, with nice new strap. I will buy again here for sure, the offer of watches is really great.

Ivana Mészáros

It took a lot of time for the package to be delivered and I still do not know if our email exchange was successful. However I received my watch as advertised and at a good price so I have no complaints in the end. These Serbs are even kind enough to save you some import taxes, so really they did me a solid.

Alexandros Sakogiannis

I thought the condition shown was almost too good to be true, but the watch is actually original as pictured and running accurately so far. I really want to emphasize the condition was immaculate for a vintage Omega. They also saved me on import fees into my country. I was really happy and surprised about that and it shows a lot of care. It’s a rare thing that I always commend shippers for.
