The Vacheron Constantin Phidias Chronograph (Reference 49001) is a highly collectible neo-vintage luxury sports watch produced between 1990 and 1995. It serves as a crucial historic milestone, acting as the direct predecessor to Vacheron Constantin's legendary Overseas collection.

  The specific variation you highlighted features a striking two-tone 18k yellow gold and stainless steel case paired with an integrated bi-color bracelet and a clean white dial.

  Named after the ancient Greek sculptor Phidias (who supervised the construction of the Parthenon), the collection bridges the gap between the historic Vacheron Constantin 222 and the modern sports watch era. 

• The Dial: The classic white dial option includes stepped chronograph sub-dials (30-minute register at 3 o'clock, 12-hour register at 9 o'clock, and running seconds at 6 o'clock) along with a date window integrated cleanly at the 6 o'clock position. Some dials from this era include "Sigma" markings, indicating the indices and hands are crafted from solid gold. 

• The Case & Bezel: It features a slim 35mm diameter case that wears slightly larger on the wrist due to its integrated lug-to-bracelet architecture. The chronograph variant is characterized by its hefty, solid 18k yellow gold bezel detailed with a tachymeter graduation scale. 

• The Bracelet: Celebrated for its unique engineering, the integrated bracelet features a signature scalloped 18k yellow gold line running through the center links, complete with a hidden double-folding deployant clasp.

• Movement: Powered by the Vacheron Constantin Caliber 1136. This high-end, automatic column-wheel chronograph movement beats at 21,600 vph and is built on the legendary ultra-thin Frédéric Piguet 1185 base.

• Dimensions: 35mm case diameter, 9.5mm case thickness, and 41mm lug-to-lug measurement.

• Power Reserve: Approximately 42 hours.
