Object description

Dial and Hands

The open-face pocket watch features a white porcelain dial bearing the script Rockford signature beneath 12 o'clock. The time is marked by black Breguet numerals, perimeter black minute marks, and secondary red Breguet numerals positioned above the large numerals at five-minute intervals.

A subsidiary seconds dial is located at 6 o'clock with a black stick-style hand. The primary time displays via a black spade-style hour hand and a slender black minute hand with a diamond flare toward the tip. Both direct observation and seller notes record a chip in the porcelain along the perimeter directly below the subsidiary seconds dial.

Evidence for this section
  • “White porcelain dial with script Rockford signature and black Breguet numerals”
  • “Outer perimeter tracks black minutes with red numerals at five-minute intervals”
  • “Visible porcelain chip at the lower perimeter of the subsidiary seconds register”
  • “The hour hand is spade-style, while the minute hand is a more simple, slender style with a slight diamond flare toward the tip. The sub second hand is a stick style. All hands are black.”

Case Construction

The watch is housed in an open-face metal case measuring 54 mm in diameter, 68 mm including the crown, and 18 mm in thickness. The seller describes the material as Silverode, quoting an external reference indicating a composition of white metals excluding silver, produced by the Philadelphia Watch Case Company.

The case construction includes a screw-on front bezel fitted with a plastic crystal and a smooth screw-on case back. According to the seller's documentation of internal markings, the case back is stamped 'Philidelphia Watch Case Co. Silverode 660014'. Visible externally is a gold-toned fluted winding crown set into a silver-toned pendant and bow.

Evidence for this section
  • “The 54 mm case is all silverode.”
  • “Case Diameter with Crown: 68”
  • “Case Thickness: 18”
  • “The crystal is plastic with a screw-on cover and a screw-on case back.”
  • “Philidelphia Watch Case Co. Silverode 660014”
  • “Fluted gold-toned winding crown fitted to a silver-toned pendant and bow”

Reported Movement and Heritage

The movement components are not visible in the front-facing photograph. According to the seller's description, the watch contains a size 18s, 17-jewel Grade 935 lever-set movement adorned with damascening patterns.

The movement plate is reported to be signed 'R.W.Co., Rockford, ILL.', '17 Jewels', and numbered 795861. The seller dates the piece to circa 1910, though verification requires reference to manufacturer production records.

Evidence for this section
  • “The movement features beautiful damascening patterns, 17 jewels, is Grade 935 size 18S, openface with a lever movement setting.”
  • “It is signed R.W.Co., Rockford, ILL., 17 Jewels, and 795861 (serial number).”
  • “Very stately, this 1910 Rockford Watch Company pocket watch keeps excellent time, at 113 years old!”

Open research questions

  • Does movement serial number 795861 correlate directly with Rockford Watch Company run lists for 1910?
  • Can direct uncased inspection confirm the specific damascening pattern and jewel settings of the Grade 935 movement?
  • Does the porcelain chip at the lower perimeter of the sub-seconds register extend under the bezel or involve hairlines across the dial plate?
