I have a Junghans Mega Atomic mantel clock (grey dial with green hands) that is about 15 years old. It worked without a glitch but recently the hand of the seconds detached itself and fell. I am looking for a repair manual that would show how to open the case (the whole front is clear plastic) without breaking it. Anyone knows where I can get this manual? Thanks.

First, reset the clock to 0:00 hours. The instant the clicking stops, pop out the battery. The second hand stem should be at 0:00 hours. The front cover can only be removed from the bottom. Put both thumbs at the bottom of the font cover and push inward, but not too forcefully (Junghans stopped selling replacement covers shortly after dropping the product line and they are nearly impossible to find). The center should lift up enough to slide a thin credit/promotion/gift card under the center tab on the bottom. Then work the card up either slide to disengage the other four tabs. The five tabs are located at the bottom center, one each on both straight sides alligned with the top of the digital display, one at 7.5 minutes, and the last one at 52.5 minutes. That is easy part. Now comes the hard one You then need to glue the second hand back onto its stem. Superglue (cyanoacrylate based) works best. The second hand must be attached perfectly level or it could scrape the cover, the clock face, and the other hands as it rotates on a tilt. Practice a few times before applying the glue. You will notice that the socket on the second hand fits the stem very loosely. Once you are ready to glue, apply one drop of superglue on the second hand socket and mount it on the centermost stem and hold it perfectly still and in proper alignment and steady for a minute or so for the glue to set. Once the glue dries, put the battery in and let it run long enough to determine if the second hand is in correct alignment. Remove the battery again. Make certain the clock face is completely free of dust and dirt before reattachment of the cover. Insert the cover from the top down snapping the five tabs into place. It may be necessary to reverse the removal process. Then you can reinsert the battery. The process worked for me when mine was accidentally knocked onto the carpet and the second hand was detached from the force of the impact. In fact, I can no longer tell which one I performed the repair on.
