- Movement Architecture and Signatures
- The watch is powered by an 18-ligne nickel-plated movement signed on a bridge with 'Borel & Courvoisier Neuchâtel' and numbered 65 047 (inscribed as 65047). The mechanism is constructed with screwed gold chatons, visible winding wheels, and a going barrel. Regulating components visible beneath the glazed cover include a cut bimetallic compensated balance with gold poising screws, a blued steel hairspring, and an index regulator with a long tail. The catalog description additionally specifies a straight-line equilibrated lever escapement and a hairspring terminal curve.
- Dial Details and Source Documentation Limits
- According to the auction listing, the front of the watch features a white enamel dial with radial Roman numerals, subsidiary seconds positioned at 6 o'clock, and blued steel Breguet hands. Because the provided visual record only displays the opened movement and inner covers, the dial and hands are not visible and rely on catalog reporting. Furthermore, the date of manufacture is reported as circa 1880–1890, representing an approximate catalog estimate rather than an archival production date.
- Case Construction and Exterior Characteristics
- This hunting-case pocket watch features an 18K yellow gold construction measuring 53 mm in diameter, with an approximate total weight of 127.2 grams. The round case incorporates a fluted case-band along its perimeter, paired with a fluted winding crown and a rounded bow. Both the solid outer cuvette and an inner glazed bezel ring swing open to reveal the movement. While the catalog record notes that the exterior cover and case back are polished and records the case number as 65 048, the outer surface details are not displayed in the single available photograph.
