Brand profile: Vacheron Constantin
Vacheron Constantin (founded 1755) is part of the 'Holy Trinity' of watchmaking and sits in the absolute luxury segment ($16,809-$560,300+). Counterfeits concentrate mainly on the Overseas, Patrimony, and historical models. The brand is counterfeited less often than Rolex/AP, but super clones from top Chinese factories (VS, ZF) reach dangerously high quality.
Key authenticity features
- Maltese Cross on the crown: On fakes it's often stamped too flat, with blurry edges and the wrong relief ratio. Genuine pieces have razor-sharp contours with a specific depth of ~0.15mm
- Guilloché depth and regularity: Machine-guilloché dials (Patrimony, Traditionnelle) show absolutely even depth on genuine pieces. Fakes have microscopic irregularities, sometimes stamped rather than cut
- Geneva Seal (if present): Must be visible on the movement with a serial number reference. Fakes often just print it on; the genuine seal is raised-engraved with a specific hallmark
- Automatic rotor movement finishing: Côtes de Genève must be perfectly parallel, edges hand-beveled (45° angle, mirror-polished). Fakes show machine bevels or uneven striping
Serial number format: VC uses 7-8 digit serial numbers, engraved between the lug ends at 6 o'clock (modern models) or on the movement plate. Format varies by production year. Modern numbers since 2000 often begin with a 2-digit year code. The model reference is additionally engraved separately (e.g. 4500V/110A-B126). The engraving must look hand-engraved with slightly irregular depth, not laser-etched. The typeface is VC's proprietary serif font with characteristic details on the digits 3, 5, 8.
