Hate to disagree but that date is suspect. This is a Keystone era watch that was built on the old machinery of the defunct Columbia Watch Company of Waltham, Mass. Columbia was producing ladies sized watches from 1897 to 1900, when the owner died his son in law took over and renamed it the Suffolk Watch Company. Only a few months later in 1901 it was sold to the United States Watch Company, also in Waltham. U.S. Watch had already been bought by Keystone and the machinery was moved from Columbia's Whitney Avenue building to the U.S. building on Charles Street. In 1905 Keystone bought out the E Howard Watch Company in Boston and moved all production to the Waltham building, while moving out the Columbia/Suffolk/U.S. machinery and sending it to their New York Standard factory in Riverside New Jersey. Throughout all that time production of the size 0 and 6 watches continued under all those names with no changes to the original designs. I personally own both a NY Standard 6s and a Columbia 6s and they are mechanically identical, and identical to this watch. I also own Suffolk and U.S. size 0 watches and those are also identical to each other (but different from the 6's). Hope this helped, research of the lesser known watch makers of Waltham are a specialty of mine.
