What distinguishes it
Look beyond the reference.
An evolution of Heuer 02, the TH20-00 combines column-wheel switching with a vertical clutch. These govern different aspects of starting and stopping the chronograph.
For the enthusiast
The long reserve is useful when rotating watches. Do not infer that every Carrera or Monaco contains this calibre: the exact model and movement reference remain essential.
