1950s Vacheron Constantin Chronograph 18K YG (Ref. 4072) 'Cal. 492'

Few watch brands are as respected or revered within the watch world as the 3rd oldest watchmaker, Vacheron Constantin, whose doors opened in 1755. Known most notably for their quality of craftsmanship and design whether it is an ultra-complicated moon phase calendar or a simple dress model. There is a reason Vacheron Constantin belongs to the “Holy Trinity” of watchmaking, and it's the brand's precise execution that transcends generations and a devotion to innovation that has solidified its regaled position within horology.

Among the many important chronographs created by Vacheron Constantin throughout the 20th century, the ref. 4072 is regarded as one of the most sought-after, researched, and coveted references created. Mostly due to its contemporary design language, especially for its era of production, along with its classic proportions and unique variations. Introduced in 1938 and produced until the early 1970s, the ref. 4072 may have been in production for about three decades, though vary sparingly, as research suggests only 1178 examples were made in total, with three different movements used throughout its lifespan. 

The example presented here employs the cal. 492 movement, based on the Valjoux caliber 22, though finished to the degree of excellence expected from Vacheron Constantin in this era. It is understood that there were only 214 examples of the ref. 4072 made featuring the cal. 492, making this example not only a marquee of horological beauty, but incredibly rare as well.
