* When Rolex reached the 999,999 production serial c. 1954 they restarted the production serial at around 10000 rather than begin a 7 digit number at system. During this period Rolex was also putting the date code on the inside of the case backs...so confusing production serials can sometimes have their production date determined. Look for the Roman number I, II, III or IV for the quarter & two arabic digits for the year.

In the 1960's, Rolex again reached the 999,999 production serial & they started their 7 digit numeric numbering system at 1,000,000 for production serials, this continued until the 1990's until production serials reached 9,999,999.

Rather than begin an 8 digit production serial, Rolex instead began their serials with a letter prefix such as R, then L, E & X. (ROLEX without the O) N, C, & S came out during the early to mid 1990's, W, T & U a little later. Around 2010 Rolex radomized the serial number system with letters mixed in with the numbers. 

Only Rolex knows the exact date that any watch was actually produced.
