Tick Talk's Guide to Spotting Vacheron & Constantin

About a year and a half ago, I posted a guide on the National Association of Watch & Clock Collectors website to provide a single point for answers to the most frequently posed questions on V&C.  With more than 14,000 views to date, it seems to address a need and now it dawns on me that some of our Lounge members may also find it useful.  I consider this an evolving article, so documented corrections and additions are always welcome. As you will see, there is also room for considered opinion and conjecture.

For the benefit of occasional visitors, please do not post your timepiece here with a request for examination or appraisal.  The former should be the subject of its own thread, while the latter contravenes forum rules. 

Happy reading!


Tick Talk's Guide to Spotting Vacheron & Constantin

In 1751, Jean-Marc Vacheron (1731 - 1805) began his trade as a watchmaker in Geneva. In 1755, he opened his own workshop and engaged an apprentice. Thus, 1755 marks the founding date for the modern company of Vacheron Constantin; the oldest continuously-operating watch Manufacture.

From 1755 to 1785, Jean-Marc Vacheron manufactured watches under the name J.M. Vacheron. His sons, Louis André and Abraham, followed their father as watchmakers. Pieces signed Louis André Vacheron appeared briefly, however it was the younger son Abraham (1760 - 1843) who carried on the family legacy, commencing in 1785, with watches signed Abraham Vacheron.

That was to change only one year later, in 1786, with the introduction of a partner, Monsieur Girod, and a new signature; Abraham Vacheron Girod, also abbreviated A. Vacheron Girod and Abm. Vacheron Girod. Girod retired in 1816 and a new partner, Charles-François Chossat, took his place. Watches were now signed Vacheron-Chossat & Cie (Cie for Compagnie).

In 1819, Abraham’s heir Jacques-Bartélémy Vacheron (1787 - 1894) and Chossat took François Constantin (1788 - 1854) into the company. Constantin had experience with sales in Italy, an important market, under Bautte of Geneva. Chossat became a silent partner and the business was renamed Vacheron & Constantin. While Vacheron continued to supervise the manufactory, Constantin took on the role of travelling salesman.

With the change of name to Vacheron & Constantin, the tradename Abraham Vacheron Girod briefly went into hibernation, to be called back in 1822 for V&C's secondary quality watches where it remained in use until the 1880s. Care must be taken to distinguish the earlier timepieces from the secondary quality watches of 1822 onwards. While the later Abm. Vacheron Girod pieces may have fusée or cylinder movements, the serial numbers are of 2xxxx and 3xxxx series. Other second quality names used by V&C included Girod Colombey, Frères Desart, Isaac Soret, Astral and Trident.

Vacheron & Constantin became so well regarded that around 1830 timepieces began to appear spuriously marked "Vacheron" and "Vacheron Frères" of Geneva (à Genève). According to the Annales de la Maison d'Horlogerie Vacheron et Constantin, this problem so vexed the Manufacture that, in 1850, when two letters were received addressed to "Vacheron Frères à Genève", this sharp response was penned; There is no maker of horology by the name of Vacheron Frères. There are many watches with this name, but they are imitations of secondary quality. There are a great many people who, not wishing to give themselves the trouble of making a name, find it useful to use that of another. You may affirm without fear that it is a false name.

Legitimate pieces marked Vacheron à Genève are very rare and construction will be consistent with their pre-1785 period, while the spurious watches from the mid-19th century onward are most often Lepine with cylinder escapements.

After a period of stability, the company name changed frequently, commencing in 1867 with the retirement of François Constantin's heir; Jean-François Constantin. Thus the company name and signature became César Vacheron & Cie, Ancienne Maison Vacheron & Constantin, after Jacques-Bartélémy's son and successor, Charles-César Vacheron (1812 - 1868).

In 1868, Charles-César died following a brief illness and the business passed to his son; Charles Vacheron (1846 - 1879). The name became Charles Vacheron & Cie. Unfortunately; Charles died 18 months later without leaving an heir. So, in 1870, the direct Vacheron family lineage ended with the widow of Charles-César and mother of Charles becoming managing director. Watches were now signed Vacheron & Constantin, Successuers Veuve César Vacheron & Cie. Veuve for widow, often abbreviated Vve. C. Vacheron & Cie.

1880 signified the registration of V&C's iconic symbol, the Maltese Cross. Other symbols used by Vacheron & Constantin over the years were the Double Horseshoes (1883) and the Trident (1884); both secondary lines.

Following the death of Madame Vacheron in 1887, the Manufacture became a Limited Company registered again as Vacheron & Constantin, although it should be noted that Mme Vacheron had returned to using the historic Vacheron & Constantin trade name on their timepieces since 1880.

American Agents for Vacheron & Constantin

Vacheron & Constantin first officially appeared on the North American continent in 1832 through the auspices of New York agent Jean Magnin and soon expanded to New Orleans and Philadelphia, and later Montreal. The agency passed through several hands, including three successive members of the Abry family. In 1894, V&C appointed Edmond E. Robert of New York as their exclusive American agent. Watch cases supplied by Robert for V&C movements frequently bear his initials E.E.R.

VXN Myth

Following the demise of the Edmond E. Robert Company in 1937, Vacheron & Constantin's marketing in the United States was taken over by Longines-Wittnauer, who also distributed LeCoultre. To comply with U.S. tariff legislation, Longines-Wittnauer was required to mark imported Swiss movements with their identifying code. Thus, the letters VXN appear on both Vacheron & Constantin and LeCoultre movements until about 1965. This does not mean they are the same! Unfortunately, for a brief time this relationship was advanced by Longines-Wittnauer to enhance sales of LeCoultre and is now used by sellers for the same purpose. An examination of the movement caliber and finish is all that is required to highlight the differences.

Merimont Watch Co.

A partnership between V&C and the American Watch Case Company began in 1917 for the American market. V&C ebauches were provided in A.W.C.CO. gold cases under the brand name "Merimont". The partnership appears to have dissolved sometime before 1927. Some authenticated examples appear after this date with V&C cases and dials but Merimont-branded movements; likely a means of using the remaining Merimont stocks.

Fabriqué Pour Vacheron & Constantin

Beginning around 1906, V&C offered more affordable watches supplied by outside manufacturers and identified as Fabriqué Pour Vacheron & Constantin (Made For Vacheron & Constantin). This strategy was adopted because V&C did not wish to sell watches bearing other maker's names, yet needed to satisfy buyers who could not yet afford a V&C.

According to V&C archives, a partial list of suppliers included Brandt & Hoffmann of Biel/Bienne, Mathey Tissot of Ponts de Martel, Georges Jules Sandoz of La Chaux-de-Fonds, H. Moser of Le Locle, Kurth Frères and Schild Frères of Granges. Smaller quantities were provided by L. Tardy and G. Sordet of Geneva


Occasionally a V&C pocket watch will appear with the cuvette inscription "Demi-Chronomètre". The official position is reflected in this statement provided by VC to the horological auction house Antiquorum: The name "Demi-Chronomètre" is used by Vacheron Constantin to indicate that the movement was sent to the Observatory for chronometric control, but that for commercial reasons, it did not remain long enough to complete the entire course of testing.

Correspondence with the Observatoire de Genève has confirmed this term was not one granted by that institution, nor will it be found in the Dictionnaire professionnel illustré de l’horlogerie. While the implication is that such a watch was equal to the rigors of Observatory testing, more probably it signifies a piece which faltered at trials and, to maintain brand prestige (perhaps the aforementioned "commercial reasons"), was withdrawn. Trials watches were purpose made and meticulously assembled; however, there was always an element of chance in the perfection of parts selected and, most significantly, the properties of alloys used in their escapements. In short, the term Demi-Chronomètre was likely created to enhance the salability of these still-exceptional watches in an attempt to recover the investment.

Merger with Jaeger-LeCoultre and Beyond

Reduced in workforce and capital by the Great Depression, Vacheron & Constantin were unprepared for the flood of orders that followed a recovery in the world's economy. The solution turned out to be a merger with Manufacture Jaeger-LeCoultre in 1938 under the holding company, Société Anonyme de Produits Industriels et Commerciaux (SAPIC). The merger ended production of in-house movements which were henceforth primarily based on JLC ebauches. Another consequence was the end of their relationship with Paris jewelers Verger Frères. Charles Constantin, great grand-nephew of François Constantin, retired from the company in 1949, leaving his nephew Léon Constantin as the sole family representative. Léon remained on the board of the firm's charitable trust, the Jules Weiss Foundation, until 1995 and thus ended the Constantin lineage which, at 175 years, surpassed the Vacheron bloodline by some three generations.

By 1965, Managing Director Georges Ketterer had amassed almost 90% of the company shares and once again made Vacheron & Constantin an independent entity. Sadly, he passed away in 1969. His son, Jacques, took hold of the reins.

In 1968 the "et" of Vacheron et Constantin was dropped from the company's advertising and by 1970 it was removed from their registered trademark. This signaled a gradual process of excising the ampersand (&) from their watches. A clear separation from the past occurred in 1974 when the company officially changed its name to Vacheron Constantin S.A. During the transition, the Manufacture used up existing stocks of components and ephemera. Indeed, as late as 1977 VC catalogs featured timepieces with both names!

Gerald Genta 222 myth

A myth persists that Gerald Genta designed the Vacheron Constantin 222 sports watch from 1977, following his great success with the so-called "jumbo" family of Patek Philippe's Nautilus 3700, Audemars Piguet's Royal Oak 5402, and IWC's Ingenieur 1832.

Unusually, this myth was initially propagated by Vacheron Constantin, who first credited Genta with the design. VC has since confirmed that their iconic 222 was, in fact, penned by a then 23-year old Jorg Hysek. Born in 1953, Hysek fled East German for Geneva at the age of seven and worked for Rolex before starting his own design company.

Modern Times

In 1986, Vacheron Constantin was sold to the former Saudi Oil Minister, Sheik Yamani.

In 1996 the brand was bought by Compagnie Financiere Richemont SA, a luxury goods holding Company. Their 2012 watch portfolio included Baume & Mercier, Cartier, IWC, Jaeger-LeCoultre, Roger Dubuis, Lange & Sohne, Montblanc, Panerai, Piaget, Vacheron Constantin, and Van Cleef & Arpels.

In 2002, Vacheron Constantin presented their first in-house movement since the 1930s; the manual caliber 1400. In 2006 they followed with an automatic caliber, the 2450. Today they are well on their way to achieving the stated goal of 100% Manufacture movements. The highlight of 2013 was their Calibre 1731 Minute Repeater; currently the thinnest available.

Vacheron Constantin CEO Juan Carlos Torres revealed their annual production for 2013 was about 30,000 watches, retailed through 300 points of sale. In October of 2013, the Manufacture announced the opening of new component production facilities in Le Brassus, Vallée de Joux. This, in addition to the expansion of their assembly and administration site located in the Geneva suburb of Plan-les-Ouates, suggests an increase of production to follow. They continue to maintain a research and prototype atelier in Le Sentier.

Thanks for the refresher Dean!

Thanks for taking the time to refresh this information for us, I believe some of the newer Loungers may not have seen it before...and I noticed there are some updates that you've made.  yes

A few questions/comments to keep things moving along angel, (and spicing things up a little devil):

1. I've seen "demi-chronometre" on a few vintage VC pocket watches and agree with what you describe.  But it is interesting that some of the WW I watches ordered by the US Corps of Engineers ordered  "Half-Chronometers" from, so I wonder how common/well-known that term was?  (Even though nothing was official and I wonder how it was defined by the Corps of Eng.)

2. Do you know anything about the history of the so called Vacheron - LeCoultre "Mystery Dial" watch.  It uses a JLC movement, but they actually inscribed  "Vacheron Constantin - LeCoultre Watches, Inc."  I believe this was a marketing trick, along with VXN, but have never seen anything definitive...so many people believe the Vacheron-LeCoultre link is more than what Longines-Wittnauer promoted.

3. As rumors go, I've just recently read people say that Hysek's design of the 222 was "inspired" by Genta.  I don't know how much of this is real.

BR, Dan

Demi-Chronometre or Half-Chronometer: which is which?
05/15/2015 - 17:27

Two great questions, Dan yes.  Thanks for taking up the spirit of this thread; to gather some of the most commonly discussed aspects of vintage V&C into one easily-accessible location.

Historically, the Swiss diverged from the English on their use of the term "chronometer".  For the Swiss, it came to mean a movement that successfully passed an independent test of timekeeping accuracy, regardless of its construction.  The pinnacle of this system were Observatory Trials.

The English viewed a chronometer as a movement that was constructed with particular features that were accepted as producing timekeeping accuracy; in particular the spring or pivoted-detent escapement.

We already understand that V&C applied "demi-chronometre" to pieces that were submitted to trials, which conforms with Swiss practice.  

The US Army Corps of Engineers order, on the other hand, specified the English term "half-chronometer", which implied a movement with lever escapement and compensation balance.  These features were considered by the English watchmakers as inferior to their ideal of a true chronometer, as evidenced by this letter submitted to the June 1882 issue of the English Mechanic and World of Science; "the term is shopkeepers' clap trap to hoodwink customers, and nothing more".

Neither demi or half-chronometer are defined in the Federation of the Swiss Watch Industry's Illustrated Professional Dictionary of Horology; they are, more or less, marketing fictions.

VXN Myth Pt II - the LeCoultre Galaxy Watch
05/15/2015 - 18:36

I would suggest these pieces fall within the VXN discussion, being LeCoultre USA products distributed by the Longines-Wittnauer Watch Co. of New York.  They are also a continuation of the Fabrique Pour Vacheron & Constantin discussion; less-expensive timepieces available with a suggestion of greater prestige.

The name of Vacheron & Constantin appears engraved on the back, alongside LeCoultre, and on the ephemera that accompanied the watch.  That is the full extend of their V&C provenance.  Their serial numbers are not to be found in the V&C archives, the case is of LeCoultre manufacture, and the movements were LeCoultre caliber 480/CW.  Yes, these pieces are the result of a collaboration with V&C, but for marketing not manufacturing.

The Script: how to read a V&C watch
05/18/2015 - 03:16

Vacheron & Constantin vintage watches have always enjoyed great interest from collectors. Here is a brief guide on what to look for to ensure your best chances of obtaining that dream watch:


On the inside of the case back will be found the Vacheron & Constantin name and Maltese Cross (A).

On pre-1950 models there will be a six-digit case serial number (B).

Those after 1950 will also have a reference / model number (C).

Vacheron & Constantin cases of precious metal will also display the casemaker's responsibility mark (D), the Helvetia symbol of Swiss manufacture (E), and assay marks for purity (F).

Reference Numbers:

Beginning in 1904, Vacheron & Constantin photographed selected timepieces of interest and assigned them photo reference numbers from 1 to 3800. This system was in place until 1937 and was only used for internal reference.

Starting in 1938, they adopted 4-digit model reference numbers for all timepieces, using 4xxx, 6xxx, and 7xxx number blocks.

Up to 1950, these reference numbers did not appear on cases at all and were only used in catalogs.  After 1950, the reference numbers were inscribed on the inside of the case back along with the case serial number.

In the mid-1970s, the numbering system expanded from 4 to 5 digits and, while the reference number continued to be inscribed inside the case, the case serial number was now engraved on the outside of the case back.

Just to throw a curve ball, in 1974 the model reference system was re-set back to 3-digits but quickly ran up to 4 again.  Thankfully, this period is beyond the "&" era.

The requirement to identify their watches as manufactured in Switzerland began around 1880 but wasn't specific to dials, so cases and movements were also marked.  However, from the earliest days, Vacheron & Constantin marked their enamel dials with GENÈVE.  SWISS was added at the 6 o'clock position on some pieces as early as 1927 and with all models by 1938.  They switched to SWISS MADE in 1972 following a change in legislation.

In 1970, the company name changed to Vacheron Constantin and the ampersand “&” was officially lost.  However, while existing stocks were used up, the “&” could appear on dials until the late 70s.


 how to read your V&C watch

After 1938, most V&C calibres were based on Jaeger-LeCoultre ebauches.  These movements will have the following characteristics:

A six digit movement number will be stamped on the base plate (A), along with the calibre designation (B) near the balance wheel. The caliber designation (C), jewel count (D), and V&C logo will be stamped on the main plate and decorated in gold. Caliber numbers (C) may be preceded by the letter "P" for Parechoc or "K" for Kif-flector.

Signs of authenticity and originality:

The finish of Vacheron & Constantin movements is outstanding and clearly separated them from most other Manufactures.  However, it is with movements that the greatest chances for Frankenstein modifications occur. Carefully examine wear to screws and bridges to see if the movement was disassembled. Check consistency of finish and alignment of Geneva stripes between parts to ensure they were assembled and finished together (E). Fine regulators (F) are often broken so compare the movement you are considering with other photos found on the internet to confirm all features are present.

Swiss movements imported into the United States between 1935 and 1965 were required to display a tariff mark.  Longines-Wittnauer Watch Co. of New York, the importer for Vacheron & Constantin, was assigned the code "VXN" (G), which was engraved on the balance cock of V & C movements destined for this market.  As the mark was shared with LeCoultre, along with base ebauches, inappropriate parts may be substituted particularly in the balance assembly.

In addition to obvious signs such as poor quality or incorrect spelling, refinished and aggressively cleaned dials may be identified by a missing accent in GENÈVE, missing "SWISS" under the 6 o'clock position, or missing "&" ampersand between Vacheron & Constantin.

Exceptions are those dials reproduced by VC during vintage restorations.  Examples have come out of their ateliers with contemporary markings VACHERON CONSTANTIN, SWISS MADE.


 how to read your V&C watch

1, 2: modern Malte style; 3: 1970s; 4: 1960s; 5: 1950s; 6: 1940s

Vacheron did not adopt the Maltese Cross-style of buckle until the late 1980's. A traditional square buckle was used prior to this. Both the buckle and strap are considered maintenance items that do not diminish value, however, the presence of original items can enhance collector value.


A Certificate of Guarantee accompanied the watch when new and lists the case and movement numbers, jewel count, date of purchase and type of metal. A Certificate of Authenticity can be obtained for a vintage watch when the original certificate has been lost. The process involves sending the watch to the Heritage Department in Geneva, and provides absolute proof of authenticity. Simple confirmation that movement and case numbers match their records can also be obtained by letter or email, however, no documentation is provided.

In 2013, Vacheron Constantin introduced an Extract from the Archives.  For a small fee, one can submit the case and movement serial numbers by mail or directly to a VC retailer.  A document will be produced which confirms the serial numbers and provides the date of completion.  This document will not assure authenticity, but will go a long way to reassuring collectors.

This is a very useful article.  Thank you for takng the time to put all of this down so clearly and thoughtfully.
