Object description

Dial and Visible Presentation

The pocket watch displays an open-face configuration with an exposed white enamel dial signed "AMERICAN WATCH CO." below the 12 o'clock position. The dial layout includes painted black Roman numeral hour markers, an outer minute track, and a recessed subsidiary seconds register at 6 o'clock. The assembly is exposed without a front crystal.

Condition issues on the dial face include visible rust and oxidation across the hour and minute hands, while the subsidiary seconds hand is missing from its post. The catalog description also notes that the enamel dial exhibits minor age-related spots and very fine hairline crazing.

Case and Accompanying Hardware

The movement is housed in an open-face Silverine case, described as a nickel-silver alloy manufactured by the Dueber Watch Case Mfg. Co. of Canton, Ohio. The case measures approximately 2.25 inches in diameter and features a hinged back cover with a circular port for key winding, with the interior recorded as stamped "DUEBER, SILVERINE, CANTON, O., 6258676" with engine-turned damaskeening.

The watch is accompanied by an attached steel bead chain with a T-bar and two winding keys, one of which has a circular head stamped with the name "WILLIAMS". Catalog notes record surface scratches, minor pitting, and wear on the case, alongside surface oxidation and wear on the keys and chain.

Reported Movement and Operating Status

Internal mechanical elements are not visible in the provided primary photograph, but the auction catalog describes an 18-size manual key-wind and key-set full-plate movement. The movement is reported to be marked "WALTHAM, MASS., P. S. Bartlett, Fogg's Patent, 2049749" and finished with an engraved balance cock and blued steel screws.

The auction description states that the watch is reported to run, but timekeeping performance, amplitude, and operational completeness have not been independently tested or verified.

Evidence for this section

“The watch features a manual key-wind and key-set full-plate movement, grade P. S. Bartlett, with Foggâ€™s Patent.”
“Movement: WALTHAM, MASS., P. S. Bartlett, Fogg's Patent, 2049749.”
“The watch is reported to run but needs a crystal.”

Open research questions

Does the movement serial number 2049749 correlate with standard American Watch Co. / Waltham production records for Model 1857 or Model 1883 18-size P.S. Bartlett runs?
Can physical examination of the movement unmounted from the case confirm whether the blued steel screws and balance assembly are completely intact?
Does the Dueber Silverine case serial number 6258676 reflect contemporary pairing with the movement or a later recasing?
