Eta 2846-2 not running

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.

Yep, wearing is the best way to check them. But now i faced the problem that one lever from remontoir is getting displaced after I take stem out. So now I need to lift the dial and so on to put the stem back...  Anyways thanks !

That‘s why with ETA movements you should only release, pull and replace the winding stem after having pulled the crown in time setting position.

Well, greetings everyone. Thanks a lot for all the help and advices. Finally I managed to finish my work on this watch. Now it has almost perfect accuracy,320 amplitude and 0.1 ms. After 1.5 years of finding parts and cracking my head on why does this watch can't work normally, I finally did it... 

Here're are two pictures of polishing.

Hope you all will have even better New year's gifts than me and your beat error want be more than 0.1 ms!

Thanks again!

the lift angle on those machines can show different rates too, your line looks clean, inbeat,  a sticky hairspring would show a lot of 'snow' for lack of a better description ....

I had a plenty of guesses about it, I don't remember when I posted those picture after or before getting the original escape wheel, fork and balance. But all in all I can say that you should never use shitty AliExpress parts (such as barrels) they are too bad to be used 😉

    • Could it be an abbreviation for Denier? "Denier (/ˈdɛniər/) or den (abbreviated D), a unit of measure for the linear mass density of fibers, is the mass in grams per 9,000 metres of the fiber. The denier is based on a natural reference: a single strand of silk is approximately one denier; a 9,000-metre strand of silk weighs about one gram." The pivot gauge looks interesting, however I wouldn't trust myself to drive a pivot into a wedge incase it jams and gets damaged/snaps trying to get it free. More a comment on my ability and incompetence than the quality or design of the tool 🤣
    • @clockboy The damage on the movement much worse. The images against the green background are my watch the other 2 are from the internet. The rotor has erased the perlage. I am surprised how is this watch still running.
    • Hi All, I recently bought a few gauges on Ebay. One of those was my actual target, a roller jewel gauge. Pictured below was one of the other gauges I received. From what I gather, this one is for measuring pivots. No sure if I'm right here. A confirmation of my assumption would be great. The gauge also has an abbreviation of "DEN". I have looked around and don't find this relative to watchmaking. Any clue to what this abbreviation means? Thanks, Don
