The second hand has fallen off. I just want to put it back. How do access the face best?

Hi Niko, the face of the watch is usually accessed from the back by removing the back cover, mechanism and the winders. I would recommend taking it to a watchsmith who will hopefully replace your second hand at a reasonable price.

If you want to try it yourself, there is a risk you may be un-"watchable" ;) How to reset watch hands

The second hand has fallen off of the shaft and has to be put back if you want to read off the minutes.

The whole front square face of the clock has 4 little nails which are located in the middle of each side (inside and next to the edge of the joint), so you have to carefully insert a screwdriver and lever the front out. After this you have to remove the hands (remember to set the clock and alarm hand to 12:00 before taking those away). The face will be loose, and you'll have access to the mechanism. Clean the alarm contact (look for a double silver metal arm that touches an small bronze stick. Alarm button can be release by gently lever the little nail that shows in the center when button is up at clock's backside.

Thank you for contacting FixYa.
Hands are fixed through the back of a watch but due to the delicate nature and complication of this type of repair, it needs to go to a watch repair service tech.

In worst case the second wheel pinion end has broken off. In best case seconds hand just fallen off the second wheel pinion and needs to be re-fitted. Rate me, plz.

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.

The second time zone hand is running on a 24 hour face (right hand half of face is morning, left hand half of face is afternoon/evening) so all you need do is multiply what it points at by two. As an example, if your second time zone hand is pointing to the right (3 o'clock) then it represents 6am and if it is pointing to the left (9 o'clock) then it represents 6pm [9 x 2 = 18:00]

it might just lightly push on but not expert at this. clocks do. and some watches do. thats a fact.

You should be able to open the back by popping it off with a sharp knife blade. Sometimes, the lip where you'd open it is hard to see and usually under the band, between the lugs. The movement will just come out. If I read you right, you know how to do this, once the movement is removed. You can't just pull the hands off. Hopefully, you'll be able to just VERY EASILY bend the one that is causing the problem.

I would highly recommend a repair shop
