The 18-Size Model 1883 movement is prominently marked with a sunrise and the word “SOL” on the barrel bridge. “Sol” is the Latin word meaning “sun.” Rube Robert Fogel was granted registration for this trademark on June 22, 1897, claiming its use in business since August 1892. The sunrise scene is also depicted on the dial.
Most of the 18-Size “Sol” movements produced at the Waltham feature gilt plates. However, this run of nickel movements represents an uncommon variant. In addition to the “Sol” watches, R.R. Fogel & Co. also sold other familiar private labels like “Cronometro Superior” and “Cronometro Victoria.”
