If you are looking for the year your Rolex watch was made, there are several places to look. The first is on the inside edge of the case back. This will tell you the model and year of manufacture. 

Where To Look On A Newer Rolex?

Check Date Stamps

A Rolex watch contains several date stamps that can help you determine the age of your look. The first place to check is on the inside edge of the case back, which will have either a four-digit or three-digit serial number. If you notice that your watch has two different dates stamped on it, it’s likely a modern model and not an older vintage one.

The second place to look is on the inside of most older models or on its clasps (if they’re solid gold) or end link (if they’re plastic). You’ll see this stamping somewhere between 2 and 8 digits long at least once every year after manufacture; if there isn’t any there—and especially if it says “CLASSIC” instead—”then chances are high that this particular Rolex was made within the last year.”

Look At The Case Reference Number

The first letter of the case reference number is the year of manufacture. The second letter is the month of manufacture, and a third letter is a three-digit number that indicates what day it was made. 

So if you have a watch with this number on its case back, it means:

  • Case 1 – January 18th, 2000 (J)
  • Case 2 – February 17th, 2001 (F)
  • Case 3 – March 16th and 17th, 2002 (G)

A case reference number is a four-digit number that identifies the watch case. It can be found inside your watch’s back cover or crown, between two numbers and letters (e.g., “42”).

The serial number is a seven-digit (sometimes eight) number found on one end of your wristwatch’s main body, usually toward its bottom or middle. If you remove your watch from its box and look at it under intense light, you should be able to see this serial number stamped into metal near where it attaches to your wristband—or even engraved into steel somewhere else on the central part if it has more than one piece!

The model name refers to what specific series was released by Rolex during that year; often, these names are used interchangeably with models within each series, but sometimes they aren’t (for example, Datejust II vs. Day-Date).

Check The Inside Edge Of The Case Back

The second place to check is on the inside edge of the case back. You’ll see a small hole in this area, which can be used as a reference point when determining what year your watch was made. The case back is usually made of stainless steel or gold, and screws are on to hold it securely in place.

Look At The End Link Of Newer Oyster Bracelets.

The third place to look is on the end link of newer oyster bracelets. These are places where it is possible for you to feel for a serial number, which will be either stamped with a large letter “S” or engraved into the metal.

Where To Look On An Old Rolex?

Case Reference Number

You’ll see this on the back of your watch when it’s time to look up its history. It’s a unique serial number that identifies each specific eye and can be found by looking at its case back. The first few characters will tell you if this is an early or late model (for example, “001”). The rest of the numbers follow suit and indicate where in production year they were made (in this case, Rolex).

Inside Edge Of The Case Back

Suppose you carefully open your wristwatch with a tiny screwdriver or similar tool. In that case, you may find some writing inside—and possibly even some other markings indicating what country it was manufactured in! If there are any words written on this piece, they’re usually stamped into metal; if not stamped into metal but rather etched in stone (like “Made In Switzerland”), then chances are pretty good that these words were added later during repair work on older models like yours.”


If you want to buy an older Rolex, there are multiple ways to tell what year it was made. The most obvious way is by looking at the case reference number inside the back. This will tell you which model and year of manufacture. If you have trouble seeing this number due to wear or damage, look directly under where the crown screws are in place (this may require removing some links from your bracelet). Then look alongside the edge near the clasp where lugs meet each other when the clasp is closed – this will give you a better view than if looking through just one hole in the back case.
