This is a lever fusses movement. Has a brass cover over the movement. Has a Heavy beveled glass crystal. Comes with a silver heavy chain. And it was made in 1892 so it is 133 years old. The heavy duty silver chain is a new chain. Comes with the original brass key to set the time on the hands. And wind the main spring. It dident have a fancy silver chain when I bought this watch. And it needed to be polished. Please note I do not sell very old hard to find antique key wound pocket watches that need no repair runs and keeps time by 20 sec. So a dealer could resale it for much more.
