Object description

Case and Bracelet Construction

The watch is described by Bonhams as an 18K gold automatic bracelet watch featuring a 35mm round case finished with brushed and polished surfaces. The cataloguing records indicate that the reverse is fitted with a screw-down back.

The timepiece is fitted with a brushed textured link bracelet closing with a folding clasp. Direct observation notes a bark-textured or woven brick-link pattern across the bracelet's exterior.

Movement Details and Documentation Limitations

The auction catalogue lists the model as Gyromatic, dating the piece to circa 1970 and specifying a jewelled automatic movement. Signatures are reported on the case, dial, and movement.

The movement and case back are not depicted in the provided auction photograph. Specific technical data—such as individual caliber reference numbers, exact jewel counts, or stamped case serial and reference numbers—are not recorded in the source description.

Evidence for this section
  • “Model: Gyromatic”
  • “Date: Circa 1970”

Open research questions

  • What specific Girard-Perregaux movement caliber is fitted within the case, and what is its stated jewel count?
  • What case reference and serial numbers are stamped on the interior or exterior of the screw-down back?
  • Is the textured gold bracelet integral to the case or attached via spring bars behind the fitted end links?
