Hi all, hope your having a good day! I have finally got back to restoring a Landeron movement, a personal project I started a while back. I believe it is an early cal. 48 although it may be a 47? The balance was one of the many issues with the watch. With a broken pivot on the staff and the balance spring beyond fixing, without buying professional tools finding a complete balance would be the easiest way for me to fix the issue. I am at a complete loss as to what balance I need; I know its a non-incabloc, possibly made by either Barbell or Renata but I'm not sure what I should be looking for, or where to find one. There are many variants and I'm not sure if any of the calibers of Landeron house the same balance that I might be able to utilise? I've attached a picture of the movement before I disassembled if it's to any use? Any help is very much appreciated! Many thanks
I am in the process of servicing the Landeron 48 movement that came with the complete watch with wrong dial applied, as many of you can recall from my other thread. After a brief check I noticed something was wrong with the balace wheel, so after inspection of the part, I discovered that the upper pivot was broken. I had another balance wheel with bent hairspring, so I decided to replace the balance wheel using the original hairpring. After a bit of tinckering, I managed to do just so, but a new problem arised, which will be shown in the linked videos here below. The first video shows how the new balance wheel turns freely after a bit of adjustment in the movement: The second video shows the problem I faced after replacing the hairspring onto the balance wheel and reassembling everything back together. Basically, the amplitude is extremely low, but I cannot figure out still what can be the problem. The second video above shows the issue better than a thousand words... I need the help of the experts, here: what can the issue be? I followed all Mark's videos on putting the watch in beat, checking the pivots, pallet stones, everything. I have never seen such behaviour before. What can it be?
