Broken Incabloc/Cap Jewel Retaining Cllip


Recommended Posts

I managed to break one half of the retaining clip on the balance bridge incabloc. (movement is a FL - Cal 253) I cleaned/oiled the cap jewel and it is being held on by on half of the retaining clip. I have assembled the movement and it is running--I have turned the movement so that the broken jewel clip is facing down and it has not fallen out of the movement.

So my "stupid" question is should I just leave it as is? This is a hobby watch so if it breaks I'll just fix it again. OR, should I spend the $18 + $4 shipping and order an new incabloc from Cousins in the U.K.????  If I get a new incabloc can I remove the clip from the new part and install in the incabloc that is already installed on the balance bridge??? I found a Youtube video that shows someone doing this--but don't know if it will work on my particular movement?? 

Any help would be a "help" as I am new to the watch hobby.

Thanks, Tracy

Hi Tracy, having just one 'arm' of the spring won't work unfortunately. A light jolt will knock the cap jewel off again. You're need to get a replacement, either a new spring or a replacement balance bridge.

While you may get lucky and replace the spring like Danh said, most likely you will need to dismantle the whole balance bridge, If I remember correctly the FL253 hairspring has an end-fixing which screws to the underside of the balance bridge so that's easy enough.

Good luck.

You have to push the incabloc  few mm out to mount a new spring, en then push it in again.

With this it is safe or you have to make it at your own with an lathe.

I think you need these as replacement.

Use rodico to mount it.

Good luck!

Thanks to all who responded to my question. I have "chickened" out about trying to replace just the incabloc clip. I'm not sure that I can successfully install the clip without pressing the cap jewel out of the balance (then I would have to get it back in). The incabloc from Cousins will cost me about $23 so i just ordered another FL cal 253 watch from ebay (yes it's from India) for $30 including shipping. Now I have spare parts for the entire movement. I may try to use the spring from the ordered watch and install on the one I'm working on--or just swap the balance between the movements.

    • Saturday morning 27/4 Sunday evening 28/4 Monday evening 29/4 Floor has a drain in the middle so I am hoping that there is very little fall on it, if any.
    • This makes much more sense now, the oil is withdrawing itself to make as little contact with the epilame as possible. Same principle as wax on a car creates a hyrophobic surface that makes the cohesive properties of water molecules pull together.  The water beads run off only when under the influence of gravity but still remain cohesively beaded up. And as mentioned earlier a pivot would keep the oil in place on a cap jewel.  Epilame on an escapement would be a different scenario, there is nothing to hold the oil in position if gravity tugs at the bead to move, plus the escape teeth pull the oil about Maybe this is why its suggested to run the watch for a short while to remove the epilame to make two oleophobic surfaces either side of the oil, creating a ring of fire 🔥 around it 😅
    • As with every skill it watchmaking, it takes practice. Notice at the top of the document it says, "Practical work - 40 hours".  I can get the balance wheels 'close enough' to flat, but never seem to get them perfect. Same with gear wheels. Guess I need more practice.
    • Has it got a beat adjustment on the platform or is it a fixed hairspring? in short what you are looking at to get it just about in beat is to get the roller jewel sitting dead centre between the banking pins. So remove the platform and take of the pallet fork and escape wheel to give you clear line of site, sit the platform with the balance in place and with it level look between the banking pins and see if the roller jewel is sitting between them, if it is nice and central its there or there abouts in beat, if its not the the position of the pinned end of the hairspring needs to be adjusted to move the roller jewel into the correct position, thats why I asked if it has an adjustment on the platform or not, if it has its an easier job. 
    • I've managed to adjust it. I'm going to try and explain it as well as I can with my limited horology knowledge but I hope it helps someone in the future. There is a cam to the right of the front plate as shown in the picture. As the clock ticks along, the pin indicated in the gear comes around and slots into one of the silencer cam gaps, turning the cam. The pin completes a full rotation in 2 hours. To adjust the cam to start at the right time set the clock to just before 7. I did 6:45. Then I turned the silencer cam anticlockwise, which spins freely, until it pushed the silencer lever up and was placed just before the drop. Just before the 7AM indicated in the picture. All I then had to do was progress the hands to 7-7:15which made the pin slot into the silencer cam gap and turn the cam so the lever comes down again, unsilencing the clock. That was it. If anyone comes across this issue again I'd be happy to assist. Thanks again to everyone that helped. Hey Transporter! Thanks a lot for the reply. That was a really good explanation and I'm sure it would have made my troubleshooting a lot less painful haha. I'm sure someone will find it useful in the future. Thank you again for taking the time to try and help me out with this.
