Rolex Production Dates

In the 1950's, Rolex reached the 999,999 production serial & started their 7 digit numeric numbering system at 1,000,000.

This continued until the 1990's when production serials reached 9,999,999.

Rather than begin an 8 digit production serial, Rolex used a letter prefix such as R, then L, E & X  - "ROLEX" without the "O".

The letter  "O" intentionally omitted to avoid any possible confusion with the number "0".

In November 1991,  a new numbering system was introduced utilizing the letters N, C and S.

In 1994, Rolex started yet another sequence with the letters: W, T  U, A, P, and K .

The latest letter prefixes run concurrently, giving the appearance of a random numbering system. This way only Rolex knows the exact date that any watch was actually produced.
