Catalogue description
Dealer description — Craft & Tailored
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.

The case retains its original unsigned crown and square pushers. The case back is also very presentable with only very light wear or markings present. The watch comes supplied on a 2pc handmade leather strap with an era-correct 18K yellow gold tang buckle. DIAL & HANDS The original two-register champagne dial featuring a telemeter and tachymeter outer timing scale and Arabic numbers at 12 and 6 o'clock is in beautifully preserved condition with only gentle elements of age present that add to the overall vintage aesthetic and charm of the timepiece. Showing only nominal marks throughout, expected for the age of the watch, with no notable spots of damage. The sub-registers show very mild aging and have aged slightly darker than the rest of the dial which is common for unrestored dials of this era. The yellow gold hour and minute hands are in superb condition, as are the accompanying blued sub-register and chronograph hands which add a welcomed cool contrast to the composition of the dial.

Atlas type guide
Chronographs and split-seconds watches
A chronograph is a watch with an additional seconds hand that can be started, stopped and returned to zero independently of the timekeeping. Louis Moinet built an early example in 1816 and Nicolas Rieussec a recording 'chronographe' in 1821; Adolphe Nicole's heart-shaped reset cam (patented 1862) made the modern return-to-zero possible. Split-seconds (rattrapante) chronographs add a second hand that can be stopped for intermediate times; flyback chronographs restart instantly.
Chronographs were essential tools for doctors (pulsometer scales), artillery (telemeter), engineers and sport. In wristwatches, Valjoux, Venus, Lemania and later the automatic chronographs of 1969 (Zenith El Primero, the Chronomatic Calibre 11 group and Seiko 6139) are milestones.
What to look for
- Push-pieces on the case band or a single button in the crown (monopusher).
- Subsidiary registers for minutes and hours; tachymeter, telemeter or pulsometer scales.
- Column wheel versus cam control visible in the movement.
- Calibre markings of specialist makers (Valjoux, Lemania, Venus, Landeron).
Dating clues
- Pocket chronographs with heart cam reset: after 1862.
- Wrist chronographs: from c. 1910; two-button designs from the 1930s.
- Automatic chronographs: from 1969.
