Dial and Visual Presentation

The watch features a double-sunk white enamel dial fitted beneath a mineral glass crystal. It displays bold black Arabic numerals along the outer perimeter, an inner recessed central disk, and a sunken subsidiary seconds register at the six o'clock position. The dial is fitted with a set of blued steel hands, comprising spade and pointer hour and minute indicators and a slender subsidiary seconds hand. As visible and reported, the dial is signed 'Illinois Bunn Special, 23 Jewel 60 Hours'. The surrounding open-face housing is constructed in white metal, showing distinctive flared shoulders that rise on either side of the winding crown, leading to an arched bow.

Reported Movement Specification

The movement is not visible in the provided imagery, but dealer records document a 16-size nickel three-quarter plate mechanism bearing serial number 5180189. It is described as a lever escapement movement equipped with a micrometer regulator, motor barrel, gold train wheels, raised gold jewel settings, and ray damascening with red enamel lettering. The plate is reported to carry the inscription: 'Sixty Hour, Bunn Special, Illinois Watch Co Springfield, Adjusted Temp & Six positions, Motor Barrel, 23 Jewels'. Based on these recorded specifications and serial numbering, the watch is catalogued by the seller as a circa 1929 Mark III Bunn Special variant.

Case Construction and Decoration

According to the seller's documentation, the watch is housed in an 'Illinois Bunn Special Model 28' white 14K gold-filled case. The case structure features a screw-on bezel and back, both finished with carved edges, while the remainder of the body presents a smooth plain surface. The vendor notes that the reverse bears an engraved monogram, and reports light wear on the underside of the bow. Measuring 52 mm in width by 14 mm in depth, the watch operates via stem winding and lever setting.
