How to disassemble this?

Recommended Posts

Hi, Its a 20-30 years old wall clock. The brand is mentioned as Supreme (Made in Japan) I spend about 20 minutes and found how to remove hands. But now I can't separate the machine from the body. I attached photos of both sides. Please help.

This looks like it unscrews? usually a screwdriver in one of the slots is sufficient to unloosen.

This type of screw ring is often seen retaining the movement to the dial.

I tried turning both directions. But looks like it is fixed.

anilv is correct it unscrews from the center. A tool fits into both slots and you unscrew, you should be able to do that with a screwdriver with a decent blade fit. I would not worry too much, on how you remove the movement as long as you do so. You just buy a new movement and fit it, they come with all the little bits and pieces and you can even choose what style of hand you would like.

I'm moving this to the Clock Corner.

Thank You. I tried using a screw drive, but didn't work. You know the name for that tool?

Tap on the screwdriver with a little hammer or anything acting as hammer, gentle, numereous taps( impacts) will eventually break loose the nut.  You may have to tap on it a lot. Needless to say, impacts are to be applied in the direction that the loosens the nut.

You may also could grab the nut with a vice-grip or pliers, (on the outside) to loosen. 

Some folks insert tweezers into both slots and turn, as long as the tweezers you use are strong enough and cheap.

Hi To get to the works, remove the two cross head screws on the back and carefully prise the back cover off, some have lugs on each side nwhich you release , but looking at the pictures it is a prise off back. they are quite easy to do and putting them back on is easy too just be carefull all is lined up and in the correct slot before closing. I have done a lot of these quartz movements and repaired most of them no problem. If it is beyond hope they are cheap enough to buy although the better quality ones are better units, Herchinger, UTS, Keinzle, Seiko etc.  good luck

Note that when sourcing a movement they come in different heights to cater to different dial materials.. Not immediately evident when buying off the internet.

    • I got this little beauty  at a swap meet on Sunday.  I changed the battery and still nothing.  I know nothing about quartz. Is there a trick I kneed to know?  Is it worth taking down to be repaired?  Should I look for an ETA movement to put inside?  It does have the gold matching band in good condition.

    • Thank you AndyHull and JerseyMo for responding with really helpful instructions!  You guys rock!  i have to get some rodic to help hold these two little mini-monsters in place. I was trying to use a small bit of sticky-tack but it didn't hold well enough.  I would get the screw into position but it would fall over when the screwdriver touched the screw.   For the 24 movement that still has the broken screw end in it, I will try to get that out after I get the lever and screw installed in my working 24.  And yes, I will install the crown/stem AFTER I have the lever and screw in place on the plate. Again, thanks for your help- i really appreciate it!!!  Will let you know when I get things back together.
