AnswerWhen purchasing a WILLIAMS AMSTERDAM timepiece from third parties such as unauthorised vendors on Amazon, eBay or Groupon, you risk receiving an unauthentic, used or defective product. To ensure full authenticity of your WILLIAMS AMSTERDAM timepiece, we highly encourage you to purchase it directly from our website or via an authorized WILLIAMS AMSTERDAM retailer.
