Watch approximately 2 ?” in diameter. Some soiling, light wear to crystal, hands move, but watch mechanism requires adjustment (the watch no longer runs). Offered with: DOYLE, Sir Arthur Conan (1859-1930). The Sign of Four. London: John Murray, [1966]. 8vo. Original wrappers (front wrapper with the same artwork as the watch; some light wear to wrappers). Later edition.
