The ability to read a chronograph instantly to the fraction of a second is one such hallmark, as is the clever use
link of space. Take, for example, the angled rehaut of the
link Carrera, a part that separates the dial from the inside of the crystal. In Heuer’s
link Carrera, it’s printed with the seconds / minutes scale – a clever use of space that effectively expands the interface without enlarging its footprint.
