Antique Early 20th Century IWC Signed Gunmetal/Gold Pocket Watch. Rare

It’s truly incredible the condition this piece is in for its age. Striking white porcelain dial, brass hands. There no cracks or chips, wow! The case is made from gunmetal and solid gold. All working as it should, no dents. Has not been polished and left completely original. Case measures. 32.80mm in width. 41.50mm in length The movement is a calibre 63 12 & 1/2 lignes produced by IWC, running lovely and keeping time. Runs first wind, winds and sets the time smoothly. The small button must be pressed when changing the time.
