- Source Reported Specifications and Condition
- The auction catalog description lists several features not fully visible in the reverse photograph, including a 15 to 16 jewel count, a cut bimetallic balance with gold timing screws, a diamond endstone, a gold lever with Lange banking, a gold wheel train, a Roman numeral white enamel dial, and blued steel hands. Condition is reported by the seller rather than verified in running order: dirty and gummy, running only with pressure applied to the train. The cataloguer also notes minor fingerprint staining and spotting, minor marring on the balance endstone setting, a dial edge flake with a faint hairline running from center to seconds bit, and oxide at the tip of the minute hand.
