Condition Report

The auction records state that the dial has been restored and the case has been repolished. The dial exhibits several small marks and the '60' graduation appears slightly faded. The gold hands, numerals, and markers show traces of oxidation and micro-scratches.

While the watch was in working order at the time of cataloguing, the auction house does not guarantee future functionality, movement accuracy, or water resistance. It is noted that parts such as the dial, hands, or movement components may not be original due to potential past services or restorations.

Evidence for this section
  • “Le cadran a été restauré.”
  • “Le boîtier a été repoli.”
  • “Cadran argenté mat: Bon état, présence de plusieurs petites marques, Le 60 légèrement effacé.”
  • “Des services ou restaurations ont pu être réalisés sur l'intégralité de la montre entraînant un remplacement des pièces qui pourraient donc ne pas être d'origine”

Open research questions

  • What is the specific nature of the dial restoration mentioned by the auction house?
  • Are there records of specific service interventions carried out on this movement?
  • To what extent has the case repolishing altered the original profile of the 33 mm case?
