Pre Owned Rolex Watch

INDEPENDENT VERIFICATION

by GemWorld International

The Swiss Crown USA process. Why partner with us?

Our process begins by hand selecting and buying only the finest quality pre-owned Rolex watches. Each watch is then inspected, refurbished and overhauled. The watch is refinished, polished and tested by technicians trained on luxury Swiss watches and backed by a two year warranty. A pre-owned Rolex certified by Swiss Crown comes with all the performance, precision and prestige you find at a fraction of the price.

 

Independent Verification

Each pre-owned Rolex watch is independently examined by Gemworld International Inc., one the the most respected gemological laboratories in the US. Each verification includes a professional photograph and shows the serial number of the pre-owned Rolex.
