Vacheron & Constantin

One of the recognised ‘Holy Trinity’ of Swiss watchmaking along with Patek Philippe and Audemars Piguet, Vacheron & Constantin is also the world’s oldest ‘Watch Manufacture’ and as such, it has remained in continuous operation since 1755. More than this, Vacheron & Constantin is the founding father of a spirit of technical excellence taken so far, it is considered an art. This is known as ‘Haute Horlogerie’ in which Vacheron & Constantin has been the leader for over 260 years. This tradition defines the Manufacture, evident in the finest quality execution, reflected in a finish which goes far beyond the demands of the ‘Poinçon de Genève’.

Created in 1886 the ‘Seal of the State of Geneva’ is the highest accolade, reserved for only the very finest quality watchmaking. Vacheron & Constantin was the first watchmaker to be allowed to use this hallmark of excellence on its movements. This, along with its extraordinarily high standards of quality and manufacture, lead many watchmakers, horologists and watch industry experts to believe Vacheron & Constantin reigns supreme among the finest quality watch manufacturers of the world.

To the collector, Vacheron & Constantin offers a level of exclusivity which even the more famous Patek Philippe can not. During the 1940s and through to the 1960s, Vacheron & Constantin only ever produced a maximum of 24 examples of each reference in any one configuration. This means that while it produced a variety of dial and case combinations, colours and designs, each one was strictly limited in number. For the collector, the fact that these watches are seriously undervalued doesn’t go unnoticed either.


For much of the history of mechanical watchmaking, slimness in watch design was considered not only aesthetically preferable, but also a clear sign of superior talent. Later in the 1950s and through to the 1970s, many watchmakers saw an increase in interest in ‘ultra-slim’ and ‘ultra-thin’ wristwatches. However, due to the many technical challenges in producing such watches, only a very few notable manufacturers achieved significant success in this area. These were Jaeger-LeCoultre, Patek Philippe, Audemars Piguet and Vacheron & Constantin.

In 1952, Vacheron & Constantin released the world’s slimmest wristwatch movement, the Calibre 1001, which was just 2.94mm thin. Then in 1955, the company did it again, taking this further by releasing the Calibre 1003, which at just 1.64mm thin was by far the thinnest wristwatch movement ever produced. Vacheron & Constantin promoted this watch as the “Flattest Watch In The World”.

The Calibre 1003 was considered so great an achievement by experts, including Vacheron & Constantin itself, that in 2015, to celebrate the 60th anniversary of its release, the company re-released the same model as the Historiques Ultra-Fine 1955, at a price of close to £30,000. This model and movement is still produced to this day and remarkably enough, despite the longevity of the Calibre 1003, its record for thinness still stands today: at 1.64mm as the world’s thinnest traditionally constructed watch movement. Many experts consider this to be the finest hand wound movement ever made.

The watch we see here is the Vacheron & Constantin model number 6115, this is an understated and yet utterly beautiful piece of history and undoubtedly one of the ultimate bargains on the market today.

The Dial

This wonderful ivory-cream dial has been fully restored to the highest standard and looks incredible. The dial carries applied gilt ‘baton’ hour indices which are matched with ‘index’ hands – so simple – yet so pleasing.

The dial is correctly signed ‘Vacheron & Constantin’ and ‘Geneve’ at the very top of the dial just below 12 with ‘Swiss’ at the very bottom, below 6.

This is the original dial which has been restored to the highest standards by our dial restorers, considered to be the best in the UK.

The Movement

The Calibre 1003 was originally conceived by Jaeger-LeCoultre as the Calibre 803, upon request from Audemars Piguet, Vacheron & Constantin. No one else, not even Jaeger-LeCoultre, has ever used this movement. Vacheron & Constantin named this its Calibre 1003 and Audemars Piguet its Calibre 2003. First introduced by Vacheron & Constantin in 1955 and still produced to this day, this remains the world’s thinnest traditionally constructed watch movement ever produced to date at 1.64mm high and 20.80mm in diameter. The 1003 is chronometer quality and requires no shock-proofing, due to its lightness. It really is one of a handful of horological accomplishments of all time. Most people do not realise that a true ‘ultra-thin’ such as this, is more difficult to produce and therefore more expensive and exclusive than most other highly complicated watches. Indeed an ultra-thin movement is considered by watchmakers as a ‘complication’. Vacheron models containing the cal.1003 today sell for over £20,000, so going vintage offers a real bargain.

The incredible calibre 1003 that you see here, inside the case, measures just 4mm. This is remarkably thin yet runs perfectly.

This example is in amazing condition having just completed a full overhaul and service by our vintage Vacheron & Constantin specialist watchmaker. It is running perfectly and has been calibrated in 5 positions to run within +14 seconds per day which is truly outstanding for any mechanical watch and has been checked and confirmed on our electronic watch timegrapher. The movement also has a power reserve of 30 hours when fully wound.

With care and regular servicing, we would fully expect this watch to continue to run very happily for many more decades to come. We are therefore totally confident in offering this watch with our 12 months’ written warranty*.

The movement is signed ‘Vacheron & Constantin’, ‘Geneve Swiss’ and ’17 Jewels’ with the Calibre number 1003 and the movement serial number 585808. The movement serial number dates this watch to 1970.

In addition, this movement carries the most highly regarded ‘Geneva Seal’. This is a distinctive hallmark depicting the Geneva coat of arms, granted by an official body at the Ecole d’Horlogerie de Genève and was only ever placed on movements which were able to achieve the most exacting standards and whose quality and finish conform to most precise and demanding specifications.

*Please note – our 12 months’ warranty is only applicable if the list price is paid.

The Watch Case

Vacheron & Constantin has been, from its very early beginnings, the torchbearer of Haute Horlogerie. This is reflected not only in its movements, but also in its watch cases. The Vacheron & Constantin model ref 6115 here measures 34mm in diameter, excluding the correct Vacheron & Constantin signed crown, and an amazing just 4mm in depth including the lens. This is remarkably thin when one considers this includes the case-back, case, movement, dial and lens. It is one of the most commercially successful, high-quality ultra-fine watches ever produced. The three-piece case design is remarkable for its rigidity and its compactness.

Few realise it today, but for the vast majority of the time the concept of a wristwatch has existed, 32mm was considered the perfect size for a gentleman’s dress watch and once the current fad for outsized watches has passed, we feel sure these smaller high-end vintage watches will become widely appreciated once again.

The case, the case-back and bezel are all in superb condition with no marks or scratches visible to the naked eye. The watch has been beautifully well cared for and after a close inspection has simply required a careful clean and a gentle polish to bring it back to its current, almost as new condition.

Inside, the case-back all is as expected, and properly signed, ‘Vacheron & Constantin’ and ‘Swiss’ with the classic Maltese Cross twice, along with Swiss Geneva 18ct hallmarks “18K 0.750″. It also carries the Vacheron & Constantin model number 6115 and the case serial number 413514. Importantly, the heavy case-back is of full thickness and has never been engraved.

As ever, our standard advice applies: vintage watches should be kept clean and dry at all times.

A new high quality black leather strap has been fitted, along with a plain gold plated buckle, which we feel suits this watch very well.
