The era opened with Heuer having a catalog of stopwatches and pocket chronographs, but only a limited selection of wrist chronographs.
In the next decades, Heuer vastly expanded the range of wrist chronographs, to become the world leader in these instruments.
Historically, Heuer produced many watches and chronographs that either had no brand name on the dial or, in some instances, showed only the name of the distributor.
From 1940, Heuer would put its name on every dial, with the movements also being marked “Ed. Heuer”.
The Heuer brand provided a strong advantage in selling the company’s range of chronographs.
