Only Rolex watches sold in the USA could have some special codes printed on the warranty paper. What do these codes mean? What are they for?On the front of a Rolex USA guarantee you can find an “Style no.” alphanumeric code made of 14 (or 9) digits.
Code: R16520A50B7839, what does it mean?
This code identifies:
3.Material used for the case
4.Colour and type of dial
5.Type of bracelet/strap etc.
|16520||Reference number of Daytona (Zenith Calibre)|
|7839||Bracelet ref. 78390|
Let’s try to understand the rule:
|(L) NNNNN(N) X NX (L XXNN)|
R = Rolex
This letter is missing when the Model reference is 6 digits long.
|NNNNN(N)||Reference code of the watch: five or six numbers, e.g. 16528, 116520 etc.|
|Material used for the case|
One letter or number:
A = Stainless steel (from French acier)
|Colour and type of the dial|
Two numbers or one number and one letter:
0U = Black Mother of Pearl with diamonds
|Type of bracelet/strap|
B = Bracelet
When the bracelet is integrated (like Oysterquartz) this code is missing.
|(XXNN)||Four numbers or two letters and two numbers, is the reference code without the last digit, e.g.:
7839 = 78390
7876 = 78760
9315 = 93150
etc.When the bracelet is integrated (like Oysterquartz) this code is missing.
