***About the Calanda Ship:
A single name, a single number: Calanda, 1. ‘Calanda’ after the eponymous cargo ship built in 1913, which flew under Switzerland’s flag from 9 April 1941. ‘1’ in a nod to the Calanda having been the very first ship to be recorded on the Swiss Boat Register, assigned Basel as its home and registration port. This was a powerful symbol for a neutral country, which had decided to equip itself with a fleet to ensure supplies could reach it by sea in light of the German and Italian troops encroaching on Greece. After many services given, the ship finally retired and was dismantled in Hong Kong in 1953.

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.

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.
