I have bought few watches from them and recommend them if you are looking to buy a watch. I as actually able to buy few watches from them that were not listed on their website. Apparently they have a lot of inventory that doesn’t even make it to the website. So if your are looking for vintage watches, you might want email them, if you can’t find it on the site.
Thank you for all the help Raymin.

I am delighted with the vintage watch that I purchased from 'Expert Watches'. It is in exactly the condition that was described with perfect patina. As a customer I could not be more delighted with the service Provided by Raymin. The communication has been
first rate and the way in which, as a first time buyer, I was helped with the details of purchase, transfer of funds and shipping was fantastic. The watch arrived on the other side of the Atlantic, expertly packaged and tracked. All in all I would thoroughly 'Expert Watches' and I will certainly be purchasing again from them to add to my vintage watch collection.
