Design

Dial and Hands

The dial is a double-sunk white enamel design fitted with a set of blued steel hands, comprising a spade hour hand, a matching minute hand, and a subsidiary seconds hand. The primary dial presents bold black upright Arabic hour numerals bordered by an outer minute track featuring prominent triangular five-minute markers. Positioned at 6 o'clock, the sunken subsidiary seconds dial is marked with black numerical tens markers and displays an arched inscription reading '23 JEWEL 60 HOUR' positioned directly above the subdial register. The seller transcribes the broader dial signature as 'Illinois Bunn Special, 23 Jewel 60 Hours'.

Visible features

• Open-face dial featuring bold black upright Arabic hour numerals and an outer minute track with prominent triangular five-minute markers. • Sunken subsidiary seconds dial positioned at 6 o'clock with black numerical tens markers and an arched inscription reading '23 JEWEL 60 HOUR' above. • Blued spade hour hand, matching blued minute hand, and a blued subsidiary seconds hand. • Two-tone metal casing displaying a yellow-toned crown and bow against a white-toned bezel with engraved border patterning.

Case Construction and Exterior Presentation

The pocket watch is housed in an open-face casing measuring 52 mm wide by 14 mm deep. The dealer documents the housing as a 'two tone 14K white and yellow gold filled case signed, Illinois Bunn Special Model 28'. Visible external examination corroborates a two-tone design, presenting a yellow-toned crown and bow against a white-toned bezel with engraved border patterning. According to the seller description, the case incorporates a screw-on bezel and back displaying 'carved edges and has flared shoulders by the bow', with the remaining surface showing a smooth plain finish and enclosing a mineral glass crystal. Subjective dealer claims asserting a 'mirror finish' and 99% mint condition reflect seller sales assessments rather than verified physical standards.

Reported Movement and Technical Specifications

The timepiece operates via stem winding and lever setting. The internal mechanism is not visible in the provided exterior photograph, and all movement specifications derive exclusively from seller reporting. The vendor catalogs a 16-size, 23-jewel nickel three-quarter plate movement equipped with a lever escapement and micrometer regulator, decorated with ray damascening, red enamel lettering, gold train wheels, and raised gold jewel settings. The dealer records the plate signature as 'Sixty Hour, Bunn Special, Illinois Watch Co Springfield, Adjusted Temp & Six positions, Motor Barrel, 23 Jewels' with serial number 5180561, attributed to circa 1929.
