Since the establishment of 1860, TAG Heuer has been praised as a model of avant-garde precision watchmaking in Switzerland. It belongs to LVMH, the world's largest luxury goods group, and is the top five luxury watch brands in the world. As a century-old pioneer of Swiss watchmaking, TAG Heuer insists on creating precise timekeeping tools and exquisite watches. Now it has two self-made movements and four watchmaking workshops, and has achieved many achievements, such as micro blade replacing hairspring, belt replacing gear, timing accuracy of 5/ 10000 seconds, double tourbillon timer, magnetic drive replacing hairspring and so on. In 20 12, TAG Heuer won the "Golden Pointer" award, the highest prize in the Geneva Advanced Watch Awards, for its CARRERA MIKROGIRDER watch which can be accurate to 5/ 10000 seconds, pushing the precision watchmaking to another peak.

The signature on the ball looks like "C Ronaldo". I don't know if it's true or not.
