Have you ever read about a Rolex Day-Date Ref. 18238, Rolex Datejust Ref. 69178, or Rolex GMT-Master Ref. 1675 and wondered what the numbers meant? If you are an avid watch enthusiast, then you know that those numbers represent the reference numbers. Reference numbers are four, five, or six digits long and the order and number each mean something different. The first two or three digits of the reference numbers are used to tell you exactly what type of watch it is. If the reference number is five digits long, then the fourth number tells the type of bezel:
The final digit in the sequence describes the type of material the Rolex watch is made of. Each number, 0-8, represents a different material:
Now that you know what the numbers mean, how do you find them? The model numbers for all Rolex watches are located at 12 o’clock in between the lugs, where the band meets the case. In order to be able to see the number, you must carefully remove the band to expose the numbers. Removing the band is very simple. Here is a step-by-step of how to remove your band:
1) Insert a jewelers screwdriver into the spring bar on the outside of either of the lugs.
2) Push up on the end piece of the band and it should come unattached.
3) Repeat these steps at the other end of the band and the bracelet should become completely unattached, exposing the model number at 12 o’clock and the serial number at 6 o’clock.
