The rock crystal plate movements were made during the late 1880s and early 1890s by William R. Willis, foreman of the jewel department at the Waltham Watch Company. According to an account about rock crystal plate watches, it is said that Mr. Willis returned from a Mexican vacation with a large quantity of agate and rock crystal. It is thought that he made approximately 200 stone movements, primarily in 6 size, with crystal back plates only. For a detailed article about watches with Waltham Crystal Plates see, the Gerrit A. Nijssen and Carl B. Goetz, NAWCC Bulletin, No. 243, "Waltham's Crystal Plates," April 2003, pp. 172-190
