Short answer
A fake Vacheron Constantin Traditionnelle copies the case shape and the name. It does not copy the movement, the gold, or the hand finishing. Five checks separate the two: caliber, case metal hallmark, dial print, caseback engraving, and paperwork.
What the genuine watch contains
Traditionnelle is a current Vacheron Constantin line. The firm dates to 1755 and works from Geneva. Genuine Traditionnelle models use in-house calibers, including the 1400, 4400 AS, 2460, and 1120. The 4400 AS runs at 21,600 vibrations per hour and holds about 65 hours of power reserve. Cases come in 18k rose gold, 18k white gold, 18k yellow gold, and platinum. Case sizes run from about 33 mm to 42 mm. Most references carry the Hallmark of Geneva, stamped on the movement.
Movement checks
An exhibition caseback shows the caliber. Genuine bridges carry Cotes de Geneve stripes, circular graining, and polished bevels. Screw heads are polished, not left rough. Engraving is sharp under a loupe. Copies often hide a plain movement behind a solid caseback, or print a rotor plate and call it decoration. A quartz movement ends the question at once. Vacheron Constantin does not put quartz in the Traditionnelle line.
Case metal and hallmarks
- Swiss 18k gold carries the St. Bernard dog head hallmark.
- Platinum carries the goat head hallmark.
- Gold-plated steel shows no precious metal stamp, or a stamp in the wrong shape.
- 18k gold has about twice the density of steel, so a gold case of equal size weighs more.
Copy cases often weigh less than a genuine gold case and more than a steel case of the same size. A scratched edge that shows grey metal under gold color is plating.
Dial, hands, and caseback
Genuine dials use applied gold indices with sharp edges. Printing is flat and dense. The Maltese cross sits at 12 o'clock on many references. Copies show fuzzy printing, glued indices, and a cross with rounded arms. Caseback engraving on the genuine watch is cut deep and even. Reference numbers and case numbers sit on the caseback and on the movement, and the two must match.
Price and paperwork
Authorized dealer prices for gold Traditionnelle models sit in the tens of thousands of US dollars. Copies sell for a few hundred dollars. Vacheron Constantin can issue an Extract from the Archives for a specific case number. A seller who cannot provide a serial number, a service history, or an archive extract is a risk.
Verification steps
- Ask for the reference and case number before payment.
- Take the watch to an authorized retailer or a watchmaker who services Vacheron Constantin.
- Open the caseback and compare the movement number to the caseback number.
- Request an Extract from the Archives from the manufacturer.
- Check the Hallmark of Geneva stamp on the movement.
