A tag heuer serial number is made up of two or three letters and four numbers and is unique to each watch. Therefore, assessing whether the model you have your eyes on follows this pattern is the first way to check the watch's authenticity by serial number.

Like a car, a Tag Heuer watch will usually depreciate about 10% per year for approximately 3 years, when it starts to plateau. Watches that increase in value are those that are desired by collectors. This is usually limited to special editions and vintage models that are more difficult to find.

In a nutshell, while the vast majority of TAG Heuer watches do not hold value in comparison to the big luxury brands like Rolex and Patek Philippe, its rare or vintage pieces do hold excellent resale value and fare better in terms of value.

Through sparking a dialogue between heritage and innovation, TAG Heuer watches blend luxury and high performance. TAG Heuer's exceptional timepieces express the very essence of Swiss watchmaking expertise, combining high standards and excellent know-how.
