The exact angle depends on the position of each component and varies between watch mechanisms, but at rest it should be roughly like this.

If the impulse jewel is not sitting in the correct place, when at rest (no power in the mainspring), the watch will be out of beat.

The exact position of the end of the hairspring relative to the jewel depends on the design of the watch, but what you show seems incorrect.

I'm still learning watch repair.  Are you saying that the impulse jewel should be directly across (180 degrees) from the beat corrector (HS terminal)?

Thank you

Early in the morning local time here. Just saw the pic.  True depends on design. 

I say,  where would you say the fork is to be placed in your watch so the BW would come to rest in beat?

It's in pieces at the moment.  This is how it looked before I took it apart and after I put it back together.  You can see the loose screw on top of the ratchet in the second pic.

Where would you place the fork so your balance wheel can come to rest in beat.

The hairspring ends right in front of the impulse pin,  HS end is where the studs mounts on the HS. That is not right.

I also thought there were something strange there, but then I realized I was looking at a shadow of the HS that looked like another turn of the spring. Could it be you're also looking at the shadow?

Well spotted, that is indeed the case. In that case the HS might be fine, but the balance may be not quite aligned correctly. Can we see the output of the time grapher?

Also, is the hairspring correctly fed through the slit in the regulator?

In the picture, it appears to go behind the regulator slot, not through it as it appears to be running too  close to the shaft of the balance to be going through the slot. This may also be an optical illusion of course.

If this is just an illusion, then , set the regulator so the mark lines up with the centre mark between the + and - indicators on the bridge. Set the beat adjuster slightly closer to the bridge, as per the ranf example I linked to, and try again.

the stud should be on spoke, almost 90deg off. That alone is enough for a flight to nowhere. 


This is not always the case. The stud in some case should align with a dot stamped on the outside diameter of the balance wheel. If this is present, it serves as a good starting point for reinstalling the HS or checking initial beat with the BW out of the movement

      Seitz Tool - Help determine if Seitz or not

      By Hawaiikook808 · Posted

      Thanks, ManSkirtBrew.  I started looking for a setup like yours and ran across this.  It was about half the price of the JKA Feintaster (depending on what auction you were in), and it's a Bergeon.  I bought it because I thought the price was fair (eBay - Buy it now), and I'm a sucker for vintage tools. It also has a table, so it should be easy to use for measuring jewels. I wonder if the the contact points can be changed out. Bergeon seems to manufacture new tables and accessories for the contemporary dial version. What do you guys think of it? I'm sorry this post seems to have taken a detour. I'm new here so let me know if I should start a new topic.

      Winding pinion making

      By nevenbekriev · Posted

      This is a flying cutter, usual one. The cutter itself is shown in the pictures in the first message, it is made of broken tungsten carbide drill bit. I asure that all the angles of the cutter are as they should be. I have video - little older one - that I made when onse making the same kind of winding pinion for a Poljot 2200, which is even smaller than this one. It is not easy to see in the video, but the tool rest moves about 1mm towards the object in Y direction and then returns back untill cutter is rotating. Then the spindle is rotated one tooth ahead and everything repeated untill all teeth are cut.

      After a bit further research could it possibly be an AS 970?

      FHF70 balance jewels settings

      By Bonefixer · Posted

      Latest project was a non-running ebay purchase with an FHF70 movement. I stripped and cleaned it, reassembled it, and got it running. So far so good, nothing damaged AFAIK.  I was oiling the top jewel on the balance (the one in the cock) which was a slightly unusual shock setting. I removed the spring (3 leaves) which was part of a chaton holding the cap jewel. This left the hole jewel behind which I retrieved with rodico and then lost it. I was taking it off the rodico, very gently as I thought, with tweezers, and then it just disappeared.  Fast forward a week, I got a donor movement, non-running, with the plan to just take the shock jewel that I’d lost. It was the same movement but had standard incabloc settings, and was steel rather than copper/brass.  I changed the cock and balance complete and it ran, not very well. I switched the lower jewel setting, cleaned and oiled both jewels and the replacement balance. Without the pallet fork the balance swings very nicely with a puff of air. With the fork in place, balance out, it flicks side to side nicely with power in the mainspring.  Put them together and it doesn’t run. The impulse jewel sits in the fork and it stops.      Any suggestions how I proceed? In case you didn’t follow that I have 2 FHF70 movements, nothing broken as far as I can tell, but mixing up the balance wheels and jewel settings results in a non runner.
