Watch Repair

Hello,
I am working on a 11AC with a bad hairspring. I have a donor movement with a good balance assembly. Will it be out of beat with a different balance or are they pretty close in matching?
Thanks

Have two that need re dial anyone know of a good place to get these done?

 I have a 1931 woman's watch and need the crystal. The problem is it looks like the crystal was place from the inside and then was framed by another piece of metal to hold it. I cant slide a crystal into the grove. These pictures aren't great but you can see the grove. Any ideas would be great 

You can see the grove in the first pic and the metal frame in the secound.

i was wondering if it is possible to retro fit old movments with a new silicon spring...would it be worth doing? do you vibrate them just like a metal spring?are they easier to form and manipualate? hard to deform? if so then it would be better then a metal spring..also they have a better time keeping abilty...

also what is acceptable beat error..also to fix beat error,lets say the watch is perfect other than being out of beat. would be put the watch in beat..is that correct because that is the way i understood,fixing beat error..

Hello,

I am work on a 10AE and replaced the mainspring with a new one. When I wound the watch the mainspring end slips off the arbor. I tried bending the end a little tighter two different times and still slips. Any suggestions or should I punt and get another spring. The broken spring was steel and new one is alloy, I don't know of that makes a difference. It is a Bulova spring came in the cool holder. Thanks

 Hi

Can someone tell me if the movement comes out through the front? It looks like someone was prying at the ring but it seems pretty solid.

Thanks

hello i have been searching for days, driving myself nuts.,and trying different ways to clean a watch part..does anyone have a foolproof way to clean a watch movement..i been doing more watches and what i have been using isn't making the grade anymore.....i have an ultrasonic machine, a cheap one but still works...i just want to turn out a better product..and upgrade my work...ANY HELP ANY WOULD EXTREMELY HAPPY FOR...THIS MAJOR..i almost don't want to clean or repair another watch till i find something that works..

I bought a M9 Oceanographer with the Gold bezel. Watch case was very dirty, but the movement ran and kept time.  To clean it, I removed the movement which involved taking the stem/crown out. I losened the stem set screw and pulled. There was a little resistance and a click. Now I can get the stem all the way in, but the watch will not run. Hands will set, and watch will run for a few seconds. What did I do wrong?  Is there a fix??

Hi,
I recently inherited my grandfather's m6 unknown and it works for seconds at a time. It's value, I'm sure is solely sentimental, however I'm hesitant to take it just anywhere after reading various jeweler reviews. After searching on here I'm guessing it needs a good cleaning. My goal is to get it working and be able to wear it, it's a stunning piece and just the right size (oversized) for my wrist.

As soon as I figure out how to upload a picture on this site I will!

Thank you for any and all suggestions.
