Question about Watches

1 Answer

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.

    Junghans Mega Atomic Mantel Clock: I found sliding a flat optical screwdriver via the front access bottom center, I was able to lever the cover loose and then off. A card was not necessary. I did not glue the second hand back on, as the cover was so easy to rake off.

My casio 4305 watch is showing the wrong time and ive been through the instructions but its still 3 and half hrs fast


You need to reste youre watch.
you need te set the dail to 12 hour position.
Doing it by holding the a and b button together. wait about 5 second and the dials should shift to 12 o clock position.
If not use the B button to shift the secons hand, then a then b fot the minute hand, then a en then b button to shift the hour hand.
After placing all the hands on 12 you press b on time and yourewatch sjould then adjust to the right time.

How to syncronize time with clock chimes? Howard Miller banjo clock.


The hands on your clock are probably friction fit, meaning that they can be adjusted, possibly even without tools. The hour hand is usually a firm slip fit over a tube, meaning that it can be slid forward and backward an hour or more as long as you hold the minute hand steady to keep the hour shaft from turning.
The minute hand may be trickier to adjust. Sometimes, it, too, is a simple friction fit, and you can pop off the hand (remove the second hand and pull the minute hand straight up off its shaft) before setting it where it should go. Other times, however, the minute hand is on a keyed shaft and has to go on in one of two directions. It's still possible that someone could have assembled your clock incorrectly, however, making the minute hand 30 minutes out of sync with your chimes.
If neither of these ideas helps you, please describe better exactly how the time isn't matching up with the chimes. That will help us better understand the underlying issue.

I have a quartz president wall clock, I changed the battery and set the time OK but the chime needs setting and I have no instructions as it is a very old clock


These are general quartz wall clock instructions as I dont know enough about what type/style of clock you have.
  • Open the access door to the dial and hands of the clock if required. Some battery-operated clock movements are sealed inside the clock case with a back panel that is screwed in place. To gain access to the hand set knob, remove the back panel screws using the appropriate tipped screwdriver.
  • Turn the minute hand (or turn the hand set knob at the rear of the movement if access is available) carefully counterclockwise or clockwise until the correct time is reached. Keep in mind that using the hand set from the rear would require turning the knob in a clockwise direction in order for the hands to turn counterclockwise.
  • Move the hour hand carefully with your fingers near the center of the hand to the hour that the clock is striking if the striking chime is not counting the correct hour. The hour hand is a friction fit hand and will move without engaging the minute hand.
  • Replace the back panel and tighten the screws with the screwdriver if removal of the back panel was necessary to access the hand set knob.
  • Close the front access door if required.

    I live in Eastern Time Zone. My atomic clock shows map of USA in top right hand corner and it is set in Western Time Zone. How do I reset to Eastern Time Zone? I have had atomic clock for several years. I...


    The "mode" button is there to change the function of the + & - buttons.

    If you press the mode button several times you will cycle through the various setting features of the clock.

    Look for the one that sets the time zone and use the + or - buttons to select your zone.

    Some experimentation may be required!

    I purchased an old Hamilton mantel clock that did not run. I have cleaned and oiled it and now it works well except it losses five minutes per day. This has a German movement, spring escapement type,...


    This clock has a floating balance escapement.

    Hold the balance snuggly with 2 figures. Take a small screw driver and push one of the 4 legs above and attached to the disk to the "+" direction. Move it about 1/4 turn. Set the correct time and check again the next day. If the clock is still slow, move it again and set the hands. Do this until the clock is accurate.

    Disclaimer: If this movement was made in the 1970 or early 1980's (The date is a 2 digit # above the movement model number). Those years the clock manufac. (Hermle) did not do well in quality materials. The may need an overhaul or movement replacement. I can provide more information if needed.

    Invicta model 3209 watch


    Your watch is fitted with chronograph movement 5040D made by Ronda (Switzerland). If you take a closer look, then you will realise that the subdial at 3 o'clock is counting seconds allready. This is your seconds dial, not the big one.
    The big seconds hand actually is the chronograph hand (stopwatch) and, when activated, works together with 1/10th counter.
    Follow this link and see for yourself:

    http://www.ronda.ch/e/index_bedienung.html

    Find movement 5040D and click on INTERACTIVE version.

    Rate me, please.

    Wall clock not working


    If you are sure the hands are not touching as they pass, perhaps the minute hand and hour hand are binding together at the hub. Try this: Gently pull on the minute hand by gripping its hub with the nails of your finger and thumb. It should slide forward a little (or come off). Also the same for the hour hand, to ensure it is not binding on the face of the dial.
    I don't know the particular clock, but if it has a SECONDS hand, this is often the one that needs to be freed.
    If all the hands are free, all should be good. If it has a seconds hand and the clock stops when this hand is going "uphill", try a fresh battery. If this doesn't fix it, remove the seconds hand and use the clock without it. Or you could try to counterbalance the hand by adding a little weight to the opposite side... this could work, but as it increases the mass of the hand also, it still might be a problem.
    Another way might be to shorten the seconds hand..!
