Bucherer ETA 2824


Recommended Posts

This came to me via my sister in law.  I serviced it yesterday until after midnight but had to finish it today.

I have never worked on this movement.  When disassembling, I take lots of pictures, but this time--not enough.  Incomplete chronicle of the keyless works.  Well...not a problem...youtube has the answers, no?  Well, everybody I found was servicing the -2 of this movement and the keyless works are quite different.  Finally found one image on the net showing the keyless works info I needed.

I found this watch to be a little challenging to assemble.  OK...I am still a noob.  My guess is that the -2 model addresses the quirkiness of the previous version of the keyless works. 

Like a dumb@ss, I failed to install the dial support ring.  Now I am battling with myself whether to take it apart again.

This calibrated on the timegrapher in three positions to 0 s/d. Pretty impressive.

Oh, another mistake...used the wrong screw for the balance cock.  It was too long and protruded through the plate.  These kinds of errors plague me.

I have a plastic box with many small compartments used for storing pills, that I have labeled with the common parts of watch movements: balance cock, pallet fork, train wheel bridge, barrel bridge, click, keyless work, motion work etc. I put the screws from their respective parts into them to avoid mixing them up. in practice, most movements have the same screws for the bridges (balance cock, barrel bridge, train wheel bridge) so you don’t have to clean that many screws separately. Most of the time, the bridge screws, motion work plate maintaining screw, and keyless work screw are the ones that you have to separate from each other. The ratchet wheel screw, click screw, or crown wheel screw are usually distinctive enough not to be confused with the rest.

Nice piece,  We are all guilty of those kind of mistakes, tired, complacent or concentrating too much or rushing the job so take heart from the fact non of us is infaliable I know Iam not,  but put it down to old age.  I once did a pocket watch cased up then found the dust ring on the bench, a PIA so had to take it all out again.  Ah well.

    • I'm sure you will get help on here soon.  Kkramme we like new members to make an introduction before posting. A little about your self such as where you life and what got you interested in Horology  
    • I'd be grateful for recommendations of good sources of advice on getting clocks with balance spring - as opposed to pendulum - escapements 'in beat'.....
    • Well I am in a bit of a quandary. I can't find the correct colour for the dial. I even wrote to Hettich a while back hoping they would give me the colour code for the dial. The reply that I received was "We don't make those anymore." I am thinking now to silver the dial and use a water transfer decal to put minute markers and the HETTICH logo (which is the very font that this forum uses) and the Made in Germany down the bottom. Not sure of the success rate of the water transfer method, but I have no other solution for the markers and logo. Handpainting is just not an option. In trying to get the top piece of the clock polished, it has progressively lost its sharp edges. My stupid hamfisted effort. I am thinking of purchasing a replacement piece of brass and drilling new holes in it for the corner posts. Why I attempted to repolish using wet & dry and not simply using a paint remover to remove the old lacquer from the brass, I don't know. You whistle and I'll point at the idiot. I also need to purchase some sheet spring steel as the two small ratchet springs that arrest the wheel that supports the weight after it is lifted by the electromagnet are worn. The two from the donor clock that I purchased are worse. I am hoping that I will be able to manufacture new springs without having to fiddle about with tempering etc to the steel. I have some ideas on that front. How many things until the clock is no longer the original? Like an axe. Heard a woodchopper on tv once saying that he had replaced the head on his axe twice and the handle three times, but it was the same axe that he began woodchopping with. 😉 I must post more often or read back through what I have previously written. Keep repeating myself. Sigh.
    • I use the exact OD and it fits in with a little force and a pleasing 'click' so it's snug and wont rotate within the holder, but that depends on how you have set up and calibrated your printer so you may need to play with the settings/dimensions a little to allow for any discrepancies in your printer calibration. PS I just finished (2 days ago) a new revision which automatically prints the movement OD on the bottom of the holder, I'll see if I can upload it here Here is rev 4 remember to change the .pdf to .FCStd so it will open in FreeCAD - also you may need to install the LiberationSansBold font and tell FreeCAD where it lives on your PC, or change the font to something you already have on your system.
