Every watch we sell at SwissWatchExpo is guaranteed to be 100% authentic and genuine name-brand, unless otherwise specified. Our expert and certified Master watchmakers conduct rigorous reviews of each watch to ensure its authenticity before we list anything for sale. You're welcome to authenticate your watch locally at any authorized retailer. It is essential to use authorized retailers only for any questions regarding a luxury timepiece.
