    I just got a ST #0792 Acquisition battery operated clock. I just cleaned the battery contacts, put in a new battery and added the four leveling feet. The clock works great, except it runs about 3 minutes slow per day. I don't know what the proper adjustment is to speed up the clock. I found a small screw at the top of the suspension rod, just below the suspension spring. It change the height of a "pusher' that engages a wheel that seems to drive the escape wheel. I turned it counterclockwise 1/2 turn, but it didn't seem to do anything. I readjusted it 1 turn clockwise, but it lifted the "pusher" so there was no engagement with the wheel. I put the screw back in it's original position and came to the FORUM for help. I hoping this isn't a function that's controlled on the little circuit board on the battery box. HELP.

    It would be so helpful to have a photo. Do you think you might do better posting this enquiry in the electric horology section?

    I agree. I will move to the Electric Horology forum, which includes battery operated clocks. In the meantime, I second JTD's request for photos of the movement.

    The timekeeping is regulated by moving the bell shaped brass piece up or down on the pendulum rod.

    Yup. That thar is a Junghans clock. Never knew they sold it under the ST name. They're very nice, if relatively unrepairable.

    I would have thought it was a Kundo myself.

    Ah ha, now I see the markings on the bell. I adjusted it a 1/4 turn up (counterclockwise) and have to wait for the results. Thanks for the information. Do you know if there is any service manual/guide for this type clock? Thanks again. Jim

    I agree with Eric. Kundo, for sure. (Based on prior work by Junghans, Bulle, etc.).

    Thank you. I always get clock names mixed up. And I live about a mile from Horolovar, too, where I watched them cutting up aluminum plates to make those battery holders this summer. Very nice people.

    You turn it either clockwise or anti-clockwise as described in posts above.

    I see you answered your own question while I was typing.
