A watch’s model number is a unique set of numbers given to a group of watches. Model numbers are used to differentiate a watch from other timepieces made by the same manufacturer. For example, all of Rolex’s Oyster Perpetual 39mm watches with a white dial and Oyster steel metal have the same model number.

How do I find my watch model number:

  1. Papers
  2. Warranty Card
  3. Watch Case

The first way to find the model number of a watch is to consult its paperwork. The official papers that came with your watch upon purchasing it contain the watch model number. Not every brand will refer to the model number as such, for example, some brands use the term “reference number.” Make sure you understand the terminology for your watch brand.


If your watch warranty card was properly completed upon purchasing it then the model number will be listed there.


Certain brands have their watch model number printed on the case. While no two brands are the same, you might be able to find a watch model number printed on the case back of one timepiece but not on another. Below are some of the most popular watch brands and where you can find their model numbers:

  • Omega: With Omega, you have two options for finding out the watch model number. Your first option is to use the serial number on the back of the case and input it in Omega’s database which will tell you its respective model number. The second option requires a professional to open the case and read the model number inside.
  • Rolex: Obtaining the model number of Rolex watches can be tricky because it is located between the watch lugs under the bracelet/strap. In order to see the model number, the watch’s bracelet/strap needs to be removed. One lug will show the watch serial number and the other lug will have the watch model number. It is best to have the bracelet/strap removed by a professional to prevent any unnecessary damage.
  • Tudor: Similar to Rolex, Tudor watches have their model number hidden under the bracelet/strap and printed beside the lugs. You need to remove the bracelet/strap to see the model number. Your best option is to work with a watchmaker who can safely remove the bracelet/strap and allow you to read the model number.
  • Cartier: Cartier  watches have 4 digits printed on the watch case back. These 4 numbers are part of the longer watch model number and indicate what the watch case looks like. Multiple watches with the same type of case can have the same 4 numbers but be composed of different materials. You can look up the 4 digits in Cartier’s reference book on watches which can be found online or in a library. However, some of Cartier’s vintage pieces and quartz watches do not have a number on the case back.
  • Tag Heuer: Tag Heuer  model numbers are easy to find as they are printed on the back of the case. Be careful not to mix the model number with the serial number as this is on the case back as well.
  • Patek Philippe: Patek Philippe  is another brand that requires a watchmaker’s assistance to obtain the model number. The watch model number is printed inside the case while its serial number is on the case back.
  • Jaeger Le-Coultre:  Jaeger Le-Coultre have their model numbers printed on the back of the case.
  • Breitling: Breitling watches have their model numbers on the back of the case. The paper work for these watches also contains this number with additional digits that designate the specific design of the watch.

If you have vintage timepieces and contemporary watches and you can’t find their model numbers, you can consult a professional horologist who can assist you in identifying the exact model.


Here are some of the most common mistakes that people make when trying to find their watch model number:

  • They confuse their watch model number with its serial number or movement number. Serial numbers are unique to each watch and movement numbers refer to the mechanism that operates that watch.
  • Some people are hesitant to share their watch model number because of scammers who might use these numbers to make counterfeit watches. However, you can rest assured that there is no risk doing it.
