You will find the country code (012 to 906) on your Rolex certificate.
The “warranty cards” were introduced in 2007 and the country code can be found at the top under “N Client:”.
Watches before 2007 were still supplied with the paper certificate.
You will find the country code punched in next to the printed word “Warranty”.
It is also possible that you have a paper certificate for an older year of manufacture for which no numbers have been punched.
There are also certificates in circulation that have been inscribed by hand or typewritten by the concessionaire.
