Junghans trivox back removal

New postby Marcus » Sun Jun 28, 2015 12:59 am

Hello Horologists,
Marcus here, looking for any advice regarding removing the back from a Junghans Trivox clock. Have removed winding keys and feet but back will not separate. Any advice greatly appreciated. Best M

I'd like to see more photos. Never heard of this clock before, but judging from the one photo, the movement may be held in place by through bolts with the nuts under the dial. See if it has a removable bezel, and if it does, remove the hands and lift off the dial. You may then see 4 small brass nuts, loosen them and the movement will slide out backwards. Be very sure before you loosen that these are not the plate bolts, otherwise you will have gear soup in a can.
This is just a guess based on the look of the back of the thing.

all wrong. Try this from the NWACC board:

Default Re: Junghans Trivox Silentic (RE: Burkhard Rasch)

unscrew the winding knobs opposite to the way they wind, the hand set knob pulls off, the alarm knob unscrews, then unscrew the bell nut, remove the bell, there is a ring press fit to the case acts as a dust guard under the bell for the movement, this just pulls off.

now look inside where the alarm stop knob pin comes in from the top of the case, sometimes these are a split pin other have a circlip holding it in place, if it's split then just gently squeeze it together and pull the knob out, then when you look at the top piece you will see a hollow screw, unscrew this and unscrew the bottom feet and the movement will now come out of the case along with the glass and sight ring
