Cataloguing Context and Evidence Limitations

The auction catalog reports the dating as "Made circa 1970" and states the condition as "In very good condition, New Old Stock". These condition and dating claims represent auction house statements rather than verified independent technical findings.

The source does not record the movement caliber, winding mechanism, case serial number, reference number, or precious metal hallmarks. Furthermore, while an "original gold plated buckle" is reported by the cataloguer, it is not depicted in the source photography.

  • “Made circa 1970”
  • “In very good condition, New Old Stock”
  • “Fine, square shaped, 18K yellow gold wristwatch with original gold plated buckle”

  • What specific movement type and caliber (mechanical manual-wind, automatic, or quartz) powers the watch?
  • What reference numbers, serial numbers, or metal hallmarks are stamped on the interior or exterior of the case?
  • What maker markings or stamps appear on the reported gold-plated buckle?
