When it comes to motorsport and timepieces, Heuer (and later on TAG-Heuer) has been a perennial official timekeeper for good part of six decades. We can even go a lot further, to 1911, when an Heuer clock was monted on a automobile’s dashboard for the first time —for Edouard Heuer himself, no less. Since then, the brand’s engineering prowess and accuracy evolved all the way to the 1950’s, with Juan Manuel Fangio as an early adopter.

The Heuer Master Time and Heuer Monte Carlo are two legendary pieces of motorsport timekeeping, often seen together in the same mounting plate. Affixed to any car’s dashboard, these would not only help keep track of the race’s duration, but would also allow drivers to calculate speed and lap times.

This particular set dates from the early 1970’s, and is in full working order and ready to be enjoyed by the discerning motorsport enthusiast.
