I have a Junghans Mega Atomic mantel clock (grey
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.

Changing Watch Batteries
Lots of posters ask "what is the battery in my (name of watch)" with a view to changing it yourself. This is a bad idea for many reasons. You don't have the tools or knowledge to remove a rotary screw on back, or the gasket sealant for a waterproof watch. Some fashion watches have 4 traditional screw and need professional grade jeweler screwdrivers. Also, there are about 20 batteries commonly used in watches, in various sizes and internal technology, Lithium Ion, Silver Oxide and Manganese Alkaline. If you buy them, you generally have to buy 10!
Don't sweat the details. Just take the watch to your local jeweler. They have all the batteries at hand and the tools to remove the back. It is done whilst you wait for $8 to $15!

Finding replacement battery for watch (DIY).
If anyone opted out to replace battery in their own watch and do not know what type and size of battery is correct for replacement, just open your watch case back and reed and memorize all the writings on battery your watch allready has in it. All you can do now is to buy exactly the same replacement battery and you will never get it wrong. All that matters is the combination of letters and numbers on battery. Make is not important, so, it can be made by Casio, Maxell, Citizen, Ronda - you name it. Just make sure you are not buying some of those cheap, unknown maker batteries, as they usualy lasts for about few weeks and then they are gone. Choose well known makers name and the battery will power your watch for 2-7 years, depending on each particular watch movement model. In case if you lost your original watch battery, check your watch instruction manual. If you lost both - battery and manual - then there is no other way, but to visit your nearest watch repair shop and ask for help.
