POCKET WATCH MECHANISM VACHERON & CONSTANTIN, No 279712
MECHANISM The presented mechanism was likely installed in a gold two-covers case of the 'Lépine' type, as evidenced by the preserved 'original' winding crown adorned in gold. The case was probably turned in as gold scrap.
In front of us is a magnificent example of horological art, produced by the renowned and oldest continuously operating Swiss watch manufacture, Vacheron & Constantin – a famous and recognizable caliber.
The design of this caliber's watch mechanism, in all its sizes, was officially registered under No. 1 among seven other designs in the commercial registry of Switzerland by the company 'Ancienne Fabrique Vacheron & Constantin, Société Anonyme' on February 1, 1905, under No. 11718.
he mechanism of the presented "Lépine" type watch is excellently preserved, featuring a thick and high-quality gold plating. It showcases blue screws, meticulous finishing, and skeletonized bridges with chamfers.
The central bridge has a distinctive "Vacheron" design with a recess to accommodate the attachment of the seconds wheel stone. The watch has bright, clean jewels, and a polished steel regulator.
The steel overlay on the anchor wheel bridge is meant for securing an additional jewel, and the winding barrel has the Maltese cross feature. The presence of the "wolf's tooth" on the crown and barrel wheels indicates a high-class mechanism.
This mechanism belongs to "Grade No VIII," which is part of the highest price segment and features the following specifications:
  • Keyless winding, with time-setting done through the winding crown.
  • Bimetallic thermocompensating balance with gold regulating screws.
  • Swiss anchor escapement with a double roller.
  • Polished "mustache"-style anchor pallet fork with open ruby pallets.
  • Isochronous balance spring with a Breguet overcoil.
  • Maltese cross on the winding barrel.
  • "Wolf's tooth" on the crown and barrel wheels.
  • 19 jewel bearings.
  • Additional jewels on the anchor wheel and pallet fork bridges.
  • Fine finishing.
  • Precise adjustments for isochronism, temperature variations, and positional accuracy.
  • Noteworthy feature: The central bridge has a recess opposite the crown wheel.

Overall, this timepiece embodies exceptional craftsmanship and belongs to the highest caliber of watch mechanisms.
Technical specifications of the mechanism:
  • Size: 19'''
  • Diameter: 42.86 mm
  • Height: 6.85 mm
  • 19 jewels
  • Frequency: 18,000 vibrations per hour
  • Power reserve: 30 hours
Vacheron Constantin watches are recognizable by their original logo in the form of a Maltese cross. This emblem, which has become a symbol of Vacheron Constantin's eternal quest for perfection, reproduces the shape of the same component in the watch mechanism. The Maltese cross is fixed on the winding barrel cover, ensuring a constant transmission of energy from the mainspring and thereby improving the accuracy of the watch's movement.
The serial number of the mechanism, 279712, is stamped on the bridge of the barrel wheel, which, according to commonly accepted tables, corresponds to the year of production in 1903. On the dial side of the plate, the same serial number is stamped, along with a hallmark bearing the trademark registered by the company "Vacheron & Constantin, fabricants, Genève" in the Federal Council of Switzerland on December 20, 1880, under No. 354.

As for the mentioned trademark, Switzerland didn't legalize patents and trademarks particularly early. Although the use of stamps and marks dates back to antiquity, the modern concept of branding and logos emerged during the industrialization of the 19th century. France passed the first "Law on Manufacturing and Trademarks" in 1857, and soon after, the UK, Australia, the USA, and Germany followed suit.

After lengthy discussions, the Swiss Confederation finally adopted the "Marques de Fabrique" (corporate brands) law in 1879. The Swiss Federal Council reviewed the earliest trademark applications, approving the initial set on November 1, 1880. In this "first batch" of approvals, watch brands and companies predominated, and registration numbers were assigned roughly in alphabetical order.

Among others, in the very first lists from December 3 and 20, 1880, and January 28, 1881, under numbers 330, 331, 332, 354, 355, and 399, the trademarks of Vacheron & Constantin, manufacturers from Geneva, were registered.

However, according to some sources, Vacheron & Constantin began using the stamp with the depiction of the Maltese cross long before its official registration, at least as early as the 1870s.

THE DIAL + HANDS

The original white enamel dial features classic slender black Roman numerals, minute markers in the "railroad" style, and additional outer minute markers from 5 to 60 at intervals of 5, also in black. The dial is complex: the large sub-seconds dial is positioned lower than the main dial, and the sub-seconds markers from 10 to 60 are also in black.

This is a highly technological dial with a characteristic "Vacheron" feature: the soldered feet of the dial have internal threads for mounting screws. The enamel is without cracks, spiderwebbing, or restorations, but there is a minor chip at the edge of the dial around four o'clock.

The hour and minute hands are in gold and of the "Poires Stuart" (Stuart Pears) style.

The characteristics typical for Patek, Philippe & Cie calibers include the form of the balance bridge, the construction of the regulator, the overlay of the jewel, as well as the method of attaching the hairspring to the balance bridge: a flat, straight balance bridge (1) with a protrusion for securing the hairspring stud in a characteristic oval shape at "3 o'clock", a Bosley regulator (2) with two setting pins for the Breguet hairspring in the "12 o'clock" position (3), an overlay for attaching the upper jewel of the balance staff (4), and a hairspring stud seated in a slot with a polished steel overlay secured by two screws (5).

In conclusion, it is worth noting that the presented mechanism, placed in a new wristwatch case after servicing, will gain a second life and continue to bring joy to its owner for many more years. After 120 years since its first creation, there will be a kind of reincarnation of this timepiece, a masterpiece of horological art from a renowned and respected manufacture, now reborn as a qualitatively new timekeeping instrument!
