This neat old Elgin Watch is running as I write. I do not know of its time keeping capabilities. I am not able to wind the watch. I can set the time. The crystal does have scratching. The movement has the number 22151458.. The watch measures about 1 inch in diameter. The back cover which is hinged is broken off and will need repair. The band is marked Hadley 1/20 12K Gold filled. 6 /o E is marked inside the back hinged cover that is broken off.   Please see the many pictures posted and my store for many more great items.
