Object description

Visual Design and Case Geometry

The timepiece features a distinct rectangular yellow gold-tone case characterized by broad, polished hooded lug covers that enclose the strap attachment points. The dial surface is silver with applied square indices, horizontal bar markers positioned at 3 and 9 o'clock, and stylized Arabic numerals marking 12 and 6. A winding and setting crown is placed off-center along the lower right case edge at approximately the 4 to 5 o'clock position.

The dial is signed 'HAMILTON' directly beneath the 12 marker, with 'Electric' rendered in script above the 6 marker. Visual observation shows a textured dark leather strap, which the seller describes as a "vintage brown lizard strap."

Case Markings and Verification Limitations

According to the dealer's transcription, the case back is inscribed "Hamilton W. Co. Lancaster, PA. 10K Gold Field R161195 Star W. C. Co." The serial number R161195 and the case fabricator attribution to Star Watch Case Company derive solely from this dealer transcription, as neither the case back nor the movement is visible in the provided imagery.

The seller dates the piece to 1962 and asserts that the watch retains its "original crown and in the original display box." However, documentation verifying the production date and independent confirmation of the box and crown originality are not recorded in this source.

Evidence for this section
  • “Case Back Signed: Hamilton W. Co. Lancaster, PA. 10K Gold Field R161195 Star W. C. Co.”
  • “dated from 1962”
  • “original crown and in the original display box.”

Open research questions

  • What specific stamped hallmarks and patent numbers appear on the inside case back to verify the Star Watch Case Company production of case R161195?
  • Does direct examination of the Caliber 505 movement confirm original factory configuration, contact wire condition, and correct battery cell installation?
  • Can surviving Hamilton sales catalogs or ledger records verify whether 1962 was the initial catalog release year for the Everest II model?
