The Vacheron Constantin Patrimony reference 42002 in 18k yellow gold is a "neo-vintage" dress watch prized for its classical 35mm proportions and refined automatic movement. A Sigma Dial variant is particularly significant to collectors, as the small Greek " " symbols at the bottom of the dial (near "Swiss Made") indicate that the hands and hour markers are made of solid 18k gold.

• Case & Dimensions: Crafted in solid 18k yellow gold, the case measures 35mm in diameter with a slim profile of approximately 8mm to 8.5mm, making it an ideal formal dress watch.

• The Sigma Dial: Features a clean white or silvered face with raised gold baton hour markers and matching baton hands. The "Sigma" signature was a mark used by members of the APRIOR association (including Vacheron Constantin, Patek Philippe, and Rolex) to emphasize the value of precious metal components during the quartz crisis.

• Μηχανισμός: Powered by the Caliber 1312 automatic self-winding movement.

  • Jewels: 27 jewels.

  • Λειτουργίες: Hours, minutes, central seconds, and a date window at the 3 o'clock position.

  • Power Reserve: Approximately 49 hours.

• Exterior Features: Typically paired with a leather strap and an 18k yellow gold tang buckle; it includes a scratch-resistant sapphire crystal and a solid caseback.
