Price estimate?

This is my dads tag heuer that I want to get fixed, I know I can send it back to tag heuer and that’s what I want to do. It’s the James Bond watch with a blue dial as people have said and the inner right dial’s hand has fallen off and got lodged under the inner left dials hand. One of the buttons on the side as well has broken off? This happened because my sister dropped it when we were children, how much roughly do you think it would cost to send it off to have it fixed?
