1958 Heuer pre-Carrera waterproof ref. 71450, this is the best Heuer chocolate dial I ever seen, a perfect watch with 40mm. case, Valjoux 72 movement and screw back case, never find in a catalog, please help me to find more information about it!
Long sought after by collectors, a flaw in the manufacturing process resulted in the occasional fading of the dial to a shade of brown, described as “tropical dial” or “chocolate”.
The watches that begin appearing in the 1940s include some that are very much sought after classics today. Elements of models like the 71450 can be seen in later watches like the Carrera, which even shares a model reference with the earlier watch. Occasionally, these watches are referred to as pre-Carreras.
The Valjoux 72 is a three register column wheel manual wind chronograph movement which traces its origins back to the 1930s. The V72 was used in the Daytona Paul Newman and many other high end watches, but also in some lesser known brands; expect to pay a premium price for watches with this rare and celebrated movement.
Alone, it is worth more them US$500, often used as spare parts for more expensive watches, and I go further, an unmarked Valjoux 72 can be signed and turned into a Rolex, Breitling, Heuer, Jaeger and others, so be careful with identification.
It all started in 1860, with Edouard Heuer setting up a workshop in Bernese, a predominantly French-speaking area of Switzerland close to the French border, a small town even now with a population under 5000. However, it is no stranger to watch companies, having also been where Breitling was founded and having been home to Longines. Of course those companies were artisan workshops producing small numbers of mostly silver-cased pocket watches.
In 1914 Heuer made the first wristwatch for men, they used pocket-watch movements and reflected demand for wristwatches that would only increase during the First World War and after.
1920 was the first time in 12 years that an Olympic Games had been held, following the cancellations of the 1912 Stockholm and 1916 Berlin events. Heuer had some prominence as a sports timing company by this point and was pleased to be selected as the official timer of the Antwerp games. This was subsequently extended to the 1924 games in Paris and 1928 in Amsterdam: this cemented the brand marriage between timing and sports.
For today’s collectors, the heyday for Heuer really began in the mid-1930s. I think that’s also probably true for many other brands. Heuer began making pilots chronographs in 35. These were used by Air Force pilots primarily, a lot of them in the German Air Force. For most Heuer collectors, these pilot chronographs from around 1935 are the first real survivors that regularly can be found in the market today.
In the 1960s and 1970s, no brand was more prominent in motorsports timing than Heuer.
