When ladies and gentlemen want to buy a watch to show their social status, the Rolex watch usually is the first choice. A Rolex watch is quite fascinating and it is a status symbol. Rolex watches were known for its solemn, practical, not flashy style, making it very popular by celebrities.
Once you purchase 
A Rolex watch online or in a retail setting and wish to make sure that the Rolex watch that you have purchased is authentic and genuine. Please don't make the mistake of taking it to a jeweler. That's the number one mistake that customers will often make. Most people don't understand this, so once they buy a Rolex watch and want to make sure that the watch is a authentic Rolex they take it to their jeweler, whom, in most cases do not specialize in watch repair or watch authentication.
First and foremost, do some research and find a master watchmaker in your area. Ask the watchmaker if he/she specializes with luxury Time pieces such as Rolex watches. This will be the most appropriate place to take a pre-owned watch for authentication. It is the job of a watchmaker to work on watches, service watches, polish watches, and authenticate watches. Watches are their profession and specialty and this is what they do, day in and day out.
All authentic Rolex watches have serial numbers. Ask your watchmaker to remove the bracelet of your Rolex watch where both you and the watchmaker can see the model and serial numbers at the 6 or 12 o'clock position. Next your watchmaker will need to remove the back case cover and look at the mechanism inside your Rolex watch. There will be a serial number stamped on the mechanism for authentication purposes. Ultimately, until the bracelet and back case cover are removed, there is nearly no way to know for sure that your watch is authentic. This is the proper authentication process for pre-owned Rolex watches. Once this process has been completed, ask your watchmaker to put his statements about the authenticity of the watch in writing. This is Very Important. You don't want a verbal opinion, you want it in writing- and with a signature. An honest watchmaker will stand by his word and his License.
In a word, Rolex watches is as good as we all know, not only will the wearer appear to be extremely wealthy but they will also be on the cutting edge of time piece fashion with a Rolex watch.
