In 1938 Vacheron Constantin introduced one of its best known chronograph models, the reference 4072. In production for nearly three decades, this timeless chronograph with a 34mm case was made in yellow gold, pink gold, steel, and steel and gold. Over the years, three different chronograph calibres were used for this reference, namely calibres 295, 434, and 492.

The present example is from the early phase of the reference 4072's production, and is fitted with calibre 295 of which only 24 watches were ever to receive a yellow gold case. Its spectacular, multi-tone silvered dial does not feature any gold numerals, but instead all hour markers and scales are in raised black enamel. The case, of timeless proportions, is particularly well preserved with strong definition to the bezel and lugs, and a crisp hallmark on the left side of the case.

It is rare to find a gold chronograph of such refined design and such unrestored, but excellent condition by any maker from the early 1940's. This reference 4072 by Vacheron Constantin is a particularly rare gem.
