The movement is not original to the clock - the dial was drilled later to acommodate a timepiece movement, whereas your clock would have originally had a striking movement. It is interesting to note that the replacement movement is roughly of the same period as the clock, around 1900, which is quite unusual as you would expect such a replacement to be considerably later. I suppose someone grew tired of the striking. The modification affects the value massively, almost nullifies it in fact - what is more, the drilling to the dial caused a great deal of damage. The case and movement might be worth 30 or 40 euros for parts.
