International Buyers (outside USA) – Please Note: Import duties, taxes, and charges are not included in the item price or shipping cost. These charges are the buyer's responsibility. Using Ebay's Global Shipping Program will help you calculate all related duties/international shipping charges. For certain countries: If you choose our alternative shipping methods instead of Ebay's Global Shipping Program, we may ship USPS "Registered Mail" so that the package can be tracked all the way to your door - this may take up to a month to arrive, but this protects us (and you) from lost packages, packages stuck in customs etc. Please check with your country's customs office to determine what these additional costs will be prior to bidding or buying. NOTICE: IF YOU ARE AN INTERNATIONAL CUSTOMER (outside USA), NO RETURNS ARE ACCEPTED. International Buyers (outside USA): we are not responsible for any delays due to a country's handling at customs. Out of country buyers, please do not ask us to put a lower value for Customs. Timelessclassicwatches is a watch enthusiast and not an authorized dealer for any company.
