Rolex Blank Vintage Warranty paper document Bureaux Suisses Timing Certificates watches submariner 5510,5508, GMt 6542, 1675

Rolex, like other Swiss watchmakers, relied on "Bureaux Suisses - de Controle Officiel de la Marche des Chronometres (Swiss Institute for Official Chronometer Tests)"  to certify that Rolex movements met or exceeded the standards required to be designated "official chronometers." The institute is an independent testing organization that certifies watches to this day. Rolex watch movements were tested for accuracy in varying positions and temperatures. In the earlier years, their results were logged by hand or typewritten on the larger timing certificates.

Afterwards, the movements were sent back to Rolex with the certificates. Swiss watchmakers used this independent testing organization to help them establish a strong reputation for manufacturing quality timing instruments.

Sales and marketing literature touted the watches with movements as "Officially Certified Chronometers." 

These timing certificates guaranteed were included with chronometer rated watches indicating the watch case number and the movement number. They are printed on both sides with the front side having results of timing tests handwritten with fountain pen or typed. Some had stickers on the bottom specific to Rolex watches. On the back there are instructions on how to interpret the test results.

The case numbers were punched on certificates starting circa 1.35M onward.

This one is mint condition, absolutly BLANK and ready for Rolex vintages watches from 50's until beginning 60's.
