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

The bent part is the hairspring, not balance wheel.

Normally you have to order one that's made specifically for this movement (sometimes one hairspring might fit multiple movements in the same family of calibers). There might be a possibility that other hairsprings could fit this balance wheel but chances are slim and even if it fits there's still the aspect of time accuracy.

Someone very experienced might be able to "straighten" it out although it's pretty bad...

    • Besides locktite Nev, is there anything random that you use to fix in the pivot ?
    • Thanks Hector, I do think though that the problem I am experiencing is specific to Miyota movement in general and the 6T series in particular.  When you describe putting the bridge you are talking about the train wheels.  The problem here is that under that same bridge you have the 4 train wheel, the barrel, 2 extra winding related wheels and the center sweep pinion.  I can mostly put them in their holes but 2 of those (the 4th wheel and the second pinion are completely under the plate so I can't nudge them in the right position.   I managed it with a larger Miyota 8200 series but with the smaller 6T15 it is even worse. Anyway, I'll retry tomorrow evening or this week end.  This evening is going another rock climbing day (going from very light pressure on tweezers to much more force going through the fingers, although in climbing we also want to use the absolute minimum grip which won't make us fall to save the muscle and be able to climb longer routes). to add insults to injury, if you read this thread from the start, I initially messed up the disassembly as I couldn't detach the rotor.  I normally (and I think I did this time too) put all my parts in their individual compartments in the part tray and I am doing my best to be very careful about them.  But in the week and a half it took to figure out how to detach the rotor I somehow lost the screws from the bridge.  I have a few others which will be needed later.  I know they are reference 922-600 but I couldn't find what it means in general term so I don't know if I can buy replacements or an assortment of screws and replace those 2 by others.
    • Something that can happen with a lyre spring, the back of the arms can bind against the shoulders of the chaton cut out where the spring is fixed in when the spring is lifted out of the way. To stop the spring bending or breaking it needs pulling forward slightly before lifting so it clears the edge of the chaton.
    • One way is to file it by hand. Good file with sharp edge is needed. Another way is with the aid of milling attachment. There is one more way, thyat is really only on the lathe, but the arbor has to be attached perpendicular to the axis of the spindle. Will be easier to show pictures than to explain this. I must say 'Good night' as my wife is now awake and is roaring when I get closer to the computer...
    • giving up so soon? then the feelings of frustrations is common for all of us. At work I've requested a cannon? To be technically correct I like to get a black powder cannon as I think I be quite enjoyable to fire some of the watch movements off into the distance never to be seen again unfortunately I don't think I'm going to get my request. So yes we all have frustrations like I have a frustration with this discussion I don't suppose before you run away you could give us the size of the movement and a photograph of the dial side with the keyless parts.  as I'm still rather curious about who made this watch.
