About Us

National Watch and Diamond, a family owned and operated business, has been located on Jewelers’ Row in Center City Philadelphia for twenty-five years.  We buy and sell fine watches, jewelry, diamonds, silver and many other valuables nationwide.  We currently have  over 300 pre-owned Rolex watches in stock.

A sample of our  inventory can be viewed at NationalWatch.com.  We have been online for over fifteen years and have built a large and loyal customer base with our prompt, personal service. Many online sites that buy valuables are nothing more than someone in an office accepting packages.  We are able to pay substantially more for most items because of the large  customer base we have established over the last twenty five years.  

Our outstanding reputation is built on years of honesty, trust, and from buying and selling quality items at reasonable prices.

If you are buying or selling National Watch can serve your needs. Feel free to email or call us with any questions you have.
