Hello
A friend of my father gave me this old pocketwatch to see if I could repare it.
As you see in the picture, the balance wheel is extremely bent. I tried to bend it back, but i cant make it good enough.
Does anyone know where I can find a balancewheel for this Revue 30 movement? I have tried to search around online, however, I cant find any.
Is there a generic balance that would fit in here?
Best regards
Nicholas

I’m working myself through Mark Lovic’s “Watch Repair Lessons & Courses”. Before enrolling I wasn’t sure the courses would be worthwhile to me, as I had spent a huge amount of time researching the Internet on how to service watches, and had serviced several Vostok 24XX movements (very affordable movements, BTW).
Now, in hindsight, the courses have proved to be extremely valuable to me. I’ve learned things that I just haven’t been able to find elsewhere, like how to easily transfer watch oil from the bottles to the oil pots, how the get the right amount of oil onto the escape wheel teeth, how to remove rust from pinion leaves, that I shouldn’t oil the pallet fork jewel bearings (and why!). The list could be made very long.
Anyway, yesterday I finished the level 2 section of the course, named “Lubrication and Re-Assembly”, and as I beheld the magic of seeing the movement come to life again I shoot a slow-motion video of its beating heart, i.e. the balance wheel. For anyone interested you can see the video here.
Thanks for reading!

Hi all,
I broke the pivot of balance wheel on ETA 2804-2.
I bought a generic complete balance wheel with bridge for ETA 2824-2 (http://www.ebay.com/itm/262234041099?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) and tried to install it without any difficulty. There is only a difference between the new and old one is the shock assemblies (Incabloc vs Novodiac). In the photo below, the new one is the yeallow on the right hand side.
My question are:
- Is the complete balance wheel and bridge replaceable between those movements?
- If Yes, after installed, the balance wheel has swung a little bit then stop. What is the reason? How to fix it?
Thank you

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?

I'm relatively new to mechanical watches and have quickly become fascinated but have an elementary level question that hopefully someone can answer.
If the hairspring and balance wheel come to a complete stop due to the main spring running out of power, what is it about winding that sets the balance wheel back into motion? I understand the way the escapement works once it is in motion to input a small amount of energy into the balance wheel, but don't understand how winding alone sets it back into motion. I know with grandfather clocks you have to restart the pendulum manually and I'm wondering why this isn't the case for watches also. TIA.

Hello Recently I bought a knock off, old style Elma watch cleaning machine. Love it. The spring that controls the motor going up and down the support shaft is quite firm and the tension knob can be a killer on the hands. So I found a scrap piece of wooden corner trim and cut it down to 16 cm to make a brace or stop. Works great!

Good call. My preferences send me an email with a tag, but I don't know what the defaults are.
