    Fred.
    The movement in your photo is equipped with the patented "Floating Balance."

    You have to look down at the top of the balance wheel. There is an inner circular spring which moves tiny weights inward or outward inside the periphery of the balance wheel to adjust the rate. Inward for faster....outward to slow.

    Normally if the rate is poor, the movement requires service.

    This is a strange balance. There seem to be NO balance jewels, the pivots "if you can call them that are just suspended? Is this right?

    Fred. The "floating balance" was invented and patented by Hettich in Germany. Many manufacturers made copies and used them. Hettich sued. It is said that Hettich recovered enough "back" royalties and penalties to retire "comfortably on the riviera."

    The floating balance has two jewels pressed inside the tube that is free to slide up or down on the central wire. The balance assembly "floats" on the compound helical balance spring.

    If carefully cleaned and maintained, the floating balance is a remarkably good escapement. However, most examples are beyond useful life. Most can be replaced by a simple conventional balance assembly which is easily understood.

    Most repairerers find the basic movement is badly worn and in need of pivot polish and re-bushing of worn plate holes thus lacking enough power to operate the escapement with zest.

    There is 1 common problem with these things that can actually be fixed.

    the wire over which the jewels ride can develop ridges from wear. This causes all kinds of trouble of course. It is possible to replace the wire! suitable wire is sold by multiple clock parts dealers.

    From what i have learned the balance needs servicing.But in may cases the movement is worn and is causing problems.if the balance was ok before when the clock was new then its not a timing issue.Its a service issue.the balance or the movement.But yes the wire could be worn as well.
    just my 2 cents worth.

    yes, I completely agree. Most of the time the main problem is in the movement. Usual suspects like worn springs and bushings.

    my remark about the floating balance was especially focussed at the part " However, most examples are beyond useful life. Most can be replaced by a simple conventional balance assembly which is easily understood."
    replacing with different construction parts goes against my ideas of good clockmaking. Especially since a floating balance in proper working order is a very good timekeeper.

    I have one of those ceramic kitchen clocks (made by Junghans) in my bedroom. On the back is a knob that can be turned with a coin. The circumference is marked with lines, about 8 of them. Each line represents 3 seconds per 24 hours faster or slower!!!

    My movement is one of those disposable Hermle movements! It is working well enough. I only paid 2 dollars for the clock.
