Timepieces used to be strictly for the home. They were delicate and expensive. When travel became more common, mobile clocks were needed and so the more rugged carriage clock was developed. It was a pretty big innovation, but some people preferred to just slip their pocket watches into leather pouches on the dash.

Speedometer companies started making aftermarket clocks as accessories, and eventually there were a lot of players in this part of the market.

You could get clocks that mounted just about anywhere, from dashboards to steering wheels, on gearshifts, and even clipped onto rear-view mirrors. The biggest leap in car clock tech happened in the '30s and '40s, when electricity started to make mechanical clock winding obsolete. Quartz technology was another significant leap in timepiece tech, but GPS and other emerging technologies promise to usher in a new era of automotive time keeping.
