Hi

I needed a escape wheel for a omega 565 the one i had the shaft had broke at the top.

I managed to get a omega 562 donor i removed the aut0 wind and the train bridge and fitted it.

But now when i look at the spring on the balance it looks wrong and different from when i started. I have put some pics up (best i can do).

I have removed it and replaced it a few times and its the same.

When i let the spring dangle from the bridge it looks lob sided.

I have checked with the donor movement and the damn thing looks the same on that one.

Any ideas appreciated.

Sorry with my terminology, i am trying just not confident enough to use it.

And yes they both looked fine when i started and all i have done is remove the escape wheel from the donor and added the escape wheel to the other watch

cheers

You need to take it off the balance and lay it down on a bare balance cock and see how it aligns with the collet and upper jewel; as well, how does it ride along the regulator. If all aligns, non issues, if not, you need to manipulate the hairspring. Check out Marks videos on how this is done or YouTube to at least see the technique. This is not beginner stuff btw.

This is the hairspring which now looks like a bird's nest, right? Here it looks like the outer coil is snagged on the inside of the boot and has been forced above the inner coils.

Can you get pictures of the one on the donor movement? One similar to this, and one in the plane of the spring. Then one of the balance and spring assembly separated from the cock.

      Maybe a little off-topic, but it still amazes me that most people (and myself before I got into this hobby) don't realise that the movement of their watch was (in most cases) not made by the name on the dial of the watch. This is especially true of many 'fashion' watches which use the cheapest of cheap movements ($4 each) which are completely out of proportion to the overall cost of the watch ($++100s). Usually the actual manufacturer is stamped somewhere inconspicuous on the movement, usually around the balance, and this is what you need to find so you can locate spare parts or servicing manuals etc. This is like buying a top of the line Rolls Royce Phantom and learning it has a BMW engine..... oh wait a minute, it does! (6.75-liter, 460-horsepower BMW V12 engine - reference)

      I have an image of what the case is supposed to look like disassembled. then an interesting website https://www.mybulova.com/vintage-bulova-catalogs there's all sorts of interesting things here for anyone in watch repair. but for the particular subject these are the two I recommend. You can see page 7 is where I got the image of the case. Then the word apartment technical manual is really a training manual of watch repair covers wristwatches and pocket watches everybody should have a copy of this.

      they are the same movement and under the same umbrella, sometimes you will see both company marks stamped on the main plate...... https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://www.opswatches.com/a-complete-guide-to-watch-movement-manufacturers/&ved=2ahUKEwiXydnwsdqFAxVfRTABHaPZDPo4ChAWegQIAhAB&usg=AOvVaw1REXmYw__k9RBspLm7cmDV

      I agree, the bezel needs removing.  If there isn't a gap between the case and bezel for removal, it's probably screw on. If so you need to grip the bezel itself.

      Looking at the picture, the case screws appear to stop the movement moving forward  (towards the crystal) indicating that this is the way the watch needs to travel to remove it from the case, hence it appears to be a front loader, this is just a 'rule of thumb' and as ever there are many exceptions. Hence, I would be fairly confident that the front bezel needs to be removed and the movement taken out the front of the watch. Look on the bezel for a small slit, similar to what you would see on a snap-on case back to remove it then the watch movement should fall out the front of the watch.
