In 2011 the watch was acquired and show the price tag of $850.  We are the third owners of the watch and replaced the movement with another wind up movement.  The watch works and works for the women with a medium wrist. If you have a delicate wrist or a large one greater that can fit into the 2 3/8 inch band then the watch is not for you.
