At Alpina we want to make sure that you have an outstanding experience with our watches, before, during and after your purchase. For this reason we work all over the world with leading watch retailers and jewelers which we authorize to sell and service our products, both in their physical and online stores. These retailers fulfill stringent quality, service and technical standards. The only way to ensure that you buy an authentic Alpina watch with our 2 years international warranty is to purchase from an Authorized Alpina Retailer or from the Official Alpina Webstore (selected markets only). Only by purchasing your watch from an authorized Alpina retailer you are assured that:
  • You are purchasing an authentic Alpina watch, and not a copy.
  • You are covered by our 2 years international guarantee.
  • Any service will be carried out by Alpina trained and experienced watchmakers using only original Alpina parts.
  • You are receiving the service and feedback you expect when purchasing a luxury Swiss Made precision product.
When you purchase from non-authorized online and off-line merchants, you run the concrete risk of purchasing a watch which has no warranty, is pre-owned, is defect or is not authentic. Also, you might run the risk of paying for a watch, which is actually not in stock and is not delivered. Alpina does not guarantee any watch, which does not have the original, stamped by an authorised retailer, warranty papers.
