How do I make a broken clock into a mirror?

What?

Sorry but I don't follow your line of thinking.

Since the part of the clock that previously held the face is no longer working, do you want to remove it, and install a mirror instead, using the rest of the clock as a sort of frame?

Although it sounds like a neat idea, I would say that the cost of purchasing a mirror, then getting it custom cut to fit this space, plus the materials to anchor it in properly, would make this project no longer cost effective.

Flipturn, thank you for redirecting my thinking & realizing the cost. I was just wanting to keep the piece because of its size & color. Again, thank you

You're welcome. Replacement clock mechanism parts are available for purchase, but, unfortunately, once again, their price might not make the project cost effective.
