Know what you are going to buy before you buy it. Ask around, ask friends who have a Rolex and read the ads to know which watch style you want, or at least narrow it down, before you go for the big step to buy. Ask a jeweler to point out to you all the identifying markings of an original Rolex watch, so you know what you are looking for.

Work with a reputable jeweler to buy your Rolex watch. However, you should have an idea of a price range that is acceptable for the style watch you want to purchase. If the price seems high to you, then go on to the next jeweler for a price estimate. There are some watch jewelers that specialize in Rolex watches, so try to find one of these in your area.

Make your purchase of a Rolex watch from online sites or websites on the Internet, but be very careful in purchasing the Rolex watch in this manner. Ask up front for identifying characteristics of an original Rolex. Have all your negotiations of the buy in writing. Obtain the model number and serial number of the Rolex watch and have it checked out by a jeweler or Rolex dealer before you commit to making a purchase in this manner.

Ask for a certificate of authenticity with the purchase of your Rolex watch. This should list the model number, serial number, the ID and all other pertinent information regarding your Rolex watch.

Understand the warranty information when you are buying the Rolex watch. Fill out the appropriate paper work for the warranty and registration and send it in. Store this information in a safe place along with the authenticity papers as you would any other valuables.
