Here’s what consumers have asked with answers from World of Watches staff and previous consumers.
I can only attest to the Movado that I purchased. I realize that is nowhere near the $150k watch you mention, but I am very happy with my purchase. I received my watch in 3-4 days. It is authentic. The warranty card was included as was my receipt. I will definitely purchase from this company again.
About two or three years ago something went wrong at World of Watches. They canceled one of my orders and issued a full refund... then they disappeared From the internet... I missed them and then about a year ago the reappeared. Why? I have no idea. Someone asked if the watches they sell are new... YES! (NOT USED).
