The TAG Heuer Modular 45 features an original concept which is brand new in the field of connected watches: the connected module is interchangeable with an Haute Horlogerie mechanical module – 3 hands or Chronograph Tourbillon COSC certified – and offers a vast choice of materials, colors and combinations. The concept of modularity also applies to the lugs, strap and buckle. This is nothing less than a luxury watch which can be completely tailored to suit your mood.
