THE FULL STORY
The Top Time was specifically described as a watch engineered to look as good as it was resilient. In that way, it marked an evolution from the pure tool chronographs that Breitling was previously known for, and allowed the brand to compete with the Carrera line from Heuer. However, the Top Time reference 2002 also offered an innovative monobloc case, which guaranteed a higher water resistance. And some 50 years later, this example has not lost any of its attributes, with a gorgeous sunburst silver dial and a sporty 35mm case.
