Partially verified

This 18k yellow gold coin watch by Vacheron Constantin, reference 7945, measures 31 mm in diameter and is powered by the manual-winding caliber K1014 movement. Sourced as a special order placed by the Royal Court of Iran in 1970, the watch features a wide bezel chased with star motifs.

Although the auction description notes a chased case back depicting the Shah of Iran and his family, only the front dial and bezel are visible in the primary image.

Object description

Construction and Design

The Vacheron Constantin reference 7945 is an 18k yellow gold coin watch measuring 31 mm in diameter. The case features a wide bezel decorated with chased star motifs.

The dial is described as having applied baton hour markers and matching hands, signed 'VACHERON & CONSTANTIN GENEVE' below 12 o'clock and 'SWISS' at 6 o'clock.

Evidence for this section
  • “18k yellow gold coin watch”
  • “Diameter: 31 mm.”
  • “chased bezel with stars motifs”
  • “Dial signed 'VACHERON & CONSTANTIN GENEVE' below 12 o'clock and 'SWISS' at 6 o'clock.”

Movement and Attribution

The watch is powered by a manual-winding Caliber K1014 movement. The catalog states the case, movement, and dial are signed by Vacheron Constantin.

The auction description claims the piece was a special order from the Royal Court of Iran in 1970 and includes a chased case back depicting the Shah of Iran and his family, though these features are not visible in the provided imagery.

Evidence for this section
  • “Manual winding movement Cal. K1014.”
  • “Case, movement and dial signed Vacheron Constantin.”
  • “The present lot was a special order from the Royal Court of Iran in 1970.”
  • “chased case back depicting the Shah of Iran, his wife and their son.”

Documentation and Discrepancies

The auction description mentions a dial featuring the Pahlavi Crest, which is not observable in the provided images of the item.

The auction house states they do not perform service, testing, or restoration, and cannot confirm that every element of the watch is original or derived from the manufacturer.

Evidence for this section
  • “dial with the Pahlavi Crest”
  • “We do not restore, service, or test any of the watches we propose for sale”
  • “we cannot confirm that each individual element of the watch is original”

Open research questions

  • Does any archival documentation from Vacheron Constantin confirm the production of a reference 7945 specifically for the Royal Court of Iran?
  • Can the discrepancy between the reported Pahlavi Crest dial and the observed baton dial be reconciled through verified provenance?
  • Is the 'chased star' bezel motif standard for the reference 7945?
