Source Documentation and Verification Limits

The physical description derives from an auction listing by McKenzies Auctioneers accompanied by a single front three-quarter photograph. Specific technical details such as caliber reference, jewel count, and running condition are not recorded in this source.

The listing notes "Case stamped: 356," but because no rear or underside view is provided, the placement and precise execution of this marking are not visible in the available documentation.

Evidence for this section
  • “Case stamped: 356.”

Open research questions

  • What specific caliber number designates this Jaeger-LeCoultre vertical in-line mechanical movement?
  • Where is the '356' case stamp positioned on the physical clock, and does it represent a model reference or a serial number?
  • What metal alloy or plating was used to manufacture the brushed silver-tone case and base?
