Thanks guys, I've done a few watches, and I hardly ever break them now . I've been enjoying servicing old Russian watches, cheap and cheerful. But I was curious to see how different clocks are. I just took a look on the bay at Smith's they look great. There's one listed close to me (so cheap postage) and only $aud20. It's listed as a mantle but the winding key is at the back not on the face?
