I have been dealing with European Watch Company for over ten years, and have purchased several wrist watches, including IWC, Patek Philippe, Rolex, and Jaeger-LeCoultre. They were not only fairly priced but arrived in like-new condition, fully warranted by European Watch Company. This company has an attentive, knowledgeable staff, a large inventory, and is a genuine pleasure to deal with.

Just completed my 7th transaction with EWC and for the 7th time the transaction was smooth, flawless and quick. Joshua is quick to respond to any e-mails and answer any questions. Ashley knows how to complete the necessary paperwork to avoid any delays at Customs as I am located in Canada and all paperwork needs to be completed perfectly which she is an expert at. You only want to deal with the best and the team at EWC is the best. There is a Yiddish word to describe the people at EWC and that word is mensches which translates to people of integrity and honour.

After a lengthy search I located the Patek Philippe I desired at EWC, but the decision to make a high dollar purchase over the internet was a difficult one. Through numerous emails with Justin and looking at reviews of EWC I made the decision to proceed and I am now ECSTATIC. The watch is exactly as described and pictured. It was perfectly packaged and shipped FedEx overnight. My watch collection now includes the watch I have been seeking for over a year.In summary, you can deal with the EWC staff with confidence. They are professional, honest and you will receive a quality watch which will put a smile on your face.

I live in San Francisco but the EWC website is the first place I check once I get an impulse for a particular watch. EWC's website is cozy and feels like home. I enjoy the photos, presentation, description and historical notes of each item and really like their next day delivery, so I stay loyal to them. Sometimes I must wait awhile for a watch to become available but can usually find anything I want. Then there are the watches you never knew you wanted until you see them here.

Dear EWC, I have just completed my very first purchase with your company: a mint Lange Datograph. Robert was extremely help throughout the process with the item delivered nicely packed to my Hong Kong address within days. The condition of the watch was absolutely mint as described and has exceeded my expectations, even under a loupe! I will be a return customer in no time. Well done!
