Short Answer
A fake Vacheron Constantin Traditionnelle 49643 is a counterfeit of a round dress watch from the Traditionnelle line. Most copies reproduce the silhouette and the dial layout, but they cannot reproduce the case proportions, the dial finishing, or the hand-finished in-house movement. Before you pay for any example, verify the reference number, measure the case, inspect the dial at magnification, and ask for movement photos. If a seller will not supply those, treat the deal as dead.
Prerequisites
- Macro photos of a genuine Traditionnelle from the same reference family
- A 10x loupe or a phone macro lens
- Digital calipers or a steel ruler
- The full reference string and caseback engraving photos from the seller
- The official spec sheet for the exact reference you are comparing
Inspection Steps
- Ask the seller for the complete reference number stamped on the caseback. Vacheron Constantin reference strings include a case material code and a finish code. Partial numbers or a missing suffix are the first warning sign.
- Measure the case across the widest point without the crown, then measure the thickness. Compare both numbers with the official spec sheet. Counterfeit cases run thick because the copy movement occupies more vertical space.
- Check the lug shape and the lugs' taper toward the spring bar. Genuine Traditionnelle lugs are cut with a smooth curve and polished on the flanks. Copies often show a flat spot or a soft edge where the polishing wheel passed.
- Study the dial at magnification. Look at the applied markers. Genuine markers sit flat, sit level, and reflect a single crisp edge. Copies show glue haze, uneven height, or markers that tilt under raking light.
- Inspect the hands. The leaf or baton hands should be polished on the bevel and matte on the flat. Replicas usually plate the whole hand in one finish and show a blunt tip.
- Turn the crown. It should unscrew and screw down with a firm, short travel, and the winding feel should be smooth and even. Gritty or loose action points to a generic crown assembly.
- Examine the caseback engraving with the loupe. Genuine engraving has sharp interior corners and even depth. Laser-etched copies look shallow and slightly rounded at the edges.
- Request a clear movement photo with the balance in view. Look for Geneva stripes applied with consistent spacing, polished screw heads, and beveled bridges. A stamped or printed finish is a copy.
- Set the watch on a kitchen scale and compare the weight with published figures for the same case metal. Gold cases carry obvious heft. A light gold-colored case is plated brass or steel.
- Inspect the strap, stitching, and buckle separately. Many replicas ship with a genuine-grade strap to distract from the watch. Judge the watch on its own.
What Copies Usually Get Wrong
Three areas give away nearly every fake. The first is the case profile, which almost always runs thicker than the genuine watch. The second is the dial, where marker alignment and print weight differ under a loupe. The third is the movement, where decoration is cosmetic rather than functional, and where the finishing stops at the visible surfaces.
Photographs hide all three. Ask for video shot at an angle to the light, not straight-on stills.
Paperwork and Provenance
A certificate, box, and hang tag prove nothing on their own. Counterfeit packaging is common and inexpensive. Match the serial on the caseback with the serial on the certificate, then confirm the reference with an authorized dealer or a qualified watchmaker before money changes hands.
Before You Commit
Have an independent watchmaker open the caseback and give you a written opinion. The cost of that inspection is small compared with the cost of a counterfeit. If the seller refuses an inspection, walk away.
