      "The dial carries a silver guilloché finish with the hour aperture at 12 o'clock and a peripheral minute track around the dial edge",
      "Exact production numbers were never officially published by Vacheron Constantin; auction research suggests approximately 192 pieces in yellow gold and 131 pieces in platinum, placing the total around 323 watches",
