- Case Construction
- The watch is housed in an engraved round hunter case described by the seller as 10K yellow gold-filled with a protective front cover and an inner dust cuvette. Dimensional data reported by the listing records a case diameter of 46.8 mm, a diameter including the crown of 58.7 mm, and a case thickness of 10.6 mm. The case back markings are reported by the vendor as "Dueber Warranted 20 Years 971300A", indicating manufacture by Dueber. Because the case back interior and cuvette are not visible in the provided image, these markings and metal specifications remain source-reported.
- Dial and Visual Configuration
- The timepiece features a white enamel dial with black Arabic numerals and the Rockford brand signature in script placed beneath the 12 o'clock position. The dial perimeter includes a black minute track supplemented by red five-minute interval markers. A subsidiary seconds dial with a blued steel hand is positioned at 6 o'clock. The winding crown and bow are located at 3 o'clock, corresponding to the hunter case arrangement. The vendor listing includes an internal discrepancy, noting "Roman numerals" in the tabular specifications despite describing black Arabic numerals in the text overview and displaying Arabic numerals in the accompanying dial photograph.
- Movement Details and Source Attribution
- According to the source listing, the watch is powered by a Rockford Watch Co. manual-winding mechanical movement designated as Grade 330, Model 1, in a size 12s layout. The movement is documented as having 17 jewels, a double roller escapement, and crown-set operation via the pendant. The listing dates the watch to 1913 based on reported movement serial number 899491. Because the movement plates are fully enclosed within the hunter case in the provided photograph, these caliber specifications, serial markings, and dating attributions are vendor-reported rather than independently visible.
