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.
