Omega Pictograms – What Does it Mean?

Do you wonder what the Omega pictograms card is? In around the year 2000, Omega started including a pictograms card with each of their watches.

Depending on the type of Omega watch, you normally get either two or three cards. One is the warranty card, one is the pictograms card, and one is the Chronometer certificate (nowadays Master Chronometer card) if your Omega watch is Master Chronometer certified.

But what does the Omega pictograms card mean?

Omega Pictograms card

Wikipedia describes ”Pictograms” as follows:

”A pictogram, also called a pictogramme, pictograph, or simply picto, and in computer usage an icon, is an ideogram that conveys its meaning through its pictorial resemblance to a physical object.”

On this card, you will be able to see a number of different symbols. These symbols refer to the specifications of the watch, and as such, different watches will have different symbols on the card. The pictograms are presented on the back of the card, but on the front of the card you can find:

  • The reference number
  • The caliber
  • The watch serial number
