Object description

Case Architecture and Visible Presentation

The pocket watch is built in a fan-form silver housing cataloged with a width of 59 mm. Direct visual examination shows an outer hinged cover opening upward to reveal an inner cuvette engraved "Sector Watch" in cursive script.

The interior face of the case lid features radiating fluted segments resembling the leaves of an opened fan or scallop shell. A sculpted pendant and bow project laterally from the side of the housing, and stamped digits are partially visible along the inner bezel rim.

Evidence for this section
  • “CASE MATERIAL: Silver”
  • “DIAMETER: 59mm (Width)”
  • “Hinged fan-shaped outer cover opens upward, revealing a polished inner cuvette engraved 'Sector Watch' in cursive script.”
  • “Interior of the case cover is sculpted with radiating fluted segments resembling a fan or scallop shell.”
  • “A decorative sculpted bow and pendant extend laterally from the side of the case.”
  • “Case edge shows stamped numbers partially visible along the inner bezel rim.”

Dial and Mechanism Reports

Because the cuvette remains closed in the catalog photograph, the dial and caliber are concealed from view. The auction documentation records an enamel dial and a manual-wind movement, categorizing the functions as "Time Only."

The catalog essay notes that turning the crown reveals a jumping hour function, where "the hour jumps from one to the next with great precision." The movement is documented as signed "Record Watch Co. S.A., Tramelan Swiss," while both the dial and case are signed "Sector Watch." The movement and case are reported to be numbered, though the full sequences are not transcribed.

Evidence for this section
  • “DIAL: Enamel”
  • “MOVEMENT: Manual”
  • “FUNCTIONS: Time Only”
  • “when you turn the crown to set the time you will notice that the hour jumps from one to the next with great precision.”
  • “Movement signed Record Watch Co. S.A., Tramelan Swiss, Dial and case signed Sector Watch, movement and case numbered.”

Condition Details and Documentation Limits

The seller's condition notes state that the silver case exhibits light scratches and wear. The enamel dial is described as having developed patina, surface scratches, and hairline cracks, specifically located "towards the center above '30' and a couple above the '55.'"

The watch is attributed to circa the 1900s. Although cataloged as in working order at the time of writing, the movement was not tested for accuracy, and specific serial numbers for the case and movement are not recorded in the source text.

Evidence for this section
  • “CIRCA: 1900s”
  • “The case is in good condition with light scratches and signs of wear.”
  • “The dial has developed patina and has scratches.”
  • “The dial appears to have a few hair line cracks, one towards the center above "30" and a couple above the "55."”
  • “The movement is in working order at the time of cataloging, consistent with the age of the watch. The movement has not been tested for accuracy.”

Open research questions

  • What specific serial numbers are stamped on the movement plate and case rim?
  • What movement caliber or patent was utilized by Record Watch Co. S.A. for this fan-shaped jumping hour mechanism?
  • How are the minute track and hour aperture arranged across the sector enamel dial?
