Nah mate, it wasn't stupid at all, if you dont know you dont know and if you dont ask you might never know. 

But anyways, that was kinda obvious 😉

You need a truing caliper tool, see Bergeon 1883-04 tool.

That tool looks like an instrument of torture from the time of the Spanish Inquisition. I'll google about this tool, thanks !

That's expensive one actually, may be you know cheaper copies of this tool?

You can pick old good quality pre owned ones for a fraction of that. Just ask to see the condition of the nibs, ideally with both truing and poising sets of nibs, the truing one have holes in the sides and concave ends to accept the conical portion of the staff pivot.

Oh gosh that's next level of watch repair art

Doesn't hurt to think next level, you already need a pair of calipers to check if the wheel is true. You could easily pick up a pair for 20 - 30 quid, I've paid much less for a pair.

5 min/day when amplitude is 280 degr is not sticky hairspring. Can we see good picture of the hairspring? What is the regulator position? Is the hairspring original to the balance, or replaced from another one?

Hi, as I remember the problem was in the hairspring position. It was slightly not parallel to the balance cock. That what my boss told me about it

We need to know if the regulator is set to the 'minimum' and still the watch is faster than normal. When I say regulator 'to the minimum', I don't mean the fine regulation screwis turned to the minimum, but the regulator  turned back right to the stud holder. That's why I asked for a photo.

I'll be able to make a photo tomorrow only

Hello everyone, do you know is there any difference between pallet fork and escapement wheel for eta 2846 (21.600) and 2824 (28.800) ? 

According to the Jules Borel interchange site they're not interchangeable, in fact the 2846 pallet fork and escape wheel appear to be unique to that caliber.

Gosh, that could be the reason for all my sufferings. Can you please share link for this site please ?

Try here.

You first select the maker, then the caliber, then the part. It will then show you all the other calibers that use that same part.

I tried it both ways, first checking the 2824 parts which turn out to be common to a lot of other calibers, but not the 2846. Then I tried the 2846 and it seems that there are no other calibers that use those parts, so I guess they are uniquie to the 2846.

Greetings everyone. This piece of junk is now showing me different indications in different  positions. I'm in one step to crash this mechanism. Please help 😄

If you know what can cause such problem, so please let me know 

 

DD amplitude is a bit lower than DU, so you might want to clean the balance jewel on the mainplate.

When vertical, you are losing about 40° amplitude, which is expected, but the line is pretty flat.

So what is your problem ?

The real test is not the timegrapher, but wearing it for several days.

    • Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!
    • Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?
    • Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.    
    • Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?      
    • Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
