HI, all as a newbie to the clock world, i am after a bit of information about a new clock that's just arrived it's a HAC which i know is Hamburg American Clocks made in Wurtterberg and that's it, but i am interested in what kind of movement it is apart from being a single train. I have never worked on this type of spring and don't have any clamps to take the spring out or a spring winder any advice would be appreciated, thanks in advance

Paul,

It is simple time only with attached winding from back plate, when companies US and European did this for simplicity.

You need to acquire a set of steel C clamps to contain the spring while you left down the movement. You might be able to use a small hole clamp.

It is a fairly narrow spring so timepiece probably only runs a day or so on a winding.

Many of us use a piece of soft steel wire to contain the spring rather than a C-clamp. Just wind the spring, secure it with the wire wound around it and the ends twisted together. Then let down the spring into the wire.
