parts touching that aren't supposed to touch definitely would cause an issue. there not supposed to be touching there supposed to be independent which means that @VWatchie is correct that the ratchet wheel has no effect on performance. so if the ratchet wheel in your particular case is touching that is definitely going to be an issue and needs to be addressed. did you know that the Swatch group service centers do not change mainsprings? Swatch group service centers have an infinite supply of spare parts so they just change the mainspring barrel the whole thing. Plus anything else the watchmaker doesn't like just gets replaced like anything related to the escapement they just replace the components because they can.

The pivots look OK. In this position, balance may rub on the pallet bridge, the roller table may rubb on the pallet fork, the bottom of roller table may rubb on the main plate, and on the tip of the screw that fixes the bottom endstone plate, the impulse jewel may rubb on guard pin, the rounded part of the pivot may rubb on the hole jewe too. Thiss all may be due to broken, missing or moved down endstone, or the plate with the stone has some dirt or other obsticle under it. But, sometimes different odd reasons can exist, like for example someone has changed the balance from a donnor movement. All the reasons are visible and must be checked. For beginning, remove the lever and it's bridge and do the free oscillations test. -
the unfortunate reality of a lot of watch brands that do not supply parts to well any of us. not only do they not supply parts you do not have access to the technical library. Each the Swatch group brands as a separate technical library. Which strangely enough for the most part can all be accessed from each brand. So the words if you login to Omega is a way of accessing all of the other brands for the most part. Another thing I find interesting is just because you have access doesn't mean you get full access as there are various levels of access of Swatch group information. So if you don't have the right level you may not even build access the technical and you definitely wouldn't be able to order anything. so the unfortunate reality is with some watches they have to go back to the authorized service. Which is why someplace out there that used to be a website urging consumers not to purchase watches from specific brands that would not let you service your own watch I don't know if that website is still out there?

When a newbie starts to put His fingers in a clock movement, if the clock starts to tick, then the newbie's heart is full of joy, He is inpatient and wakes at night to check if the clock is still ticking... A ticking clock or watch is like a man that breaths and has pulse. And this doesn't mean that that man is healthy and able to do work. The same with the clock - if it ticks and even to the end of power reserve, this still means nothing and doesn't guarantee timekeeping at all. And the main parameter of a clock or watch health is the amplitude. As You didn't mention anything about amplitude, I guessed that it may be You case too... Yes, the amplitude is measured by degrees of rotation of the balance wheel against it's 'zero' or neutral position. And a table with the amplitude will have one additional column, for the amplitude. Actually, I don't need this table, but just to know if the amplitude is good enough or bad, at least when the main spring is fully wound. Good will mean above 250 degr., and all less than 180 will mean too bad. Yes, the guard pin and safety roller are what is shown and they would never touch when the balance swings. If they touch, this leads to friction and amplitude loss. Yes, the gap with the arrow is 0 and it is a real problem, but it is true only when the string is in horizontal position, and I believe that the picture has been taken exactly in such position. In vertical position, which is normal for the balance, the mass of the balance wheel must straighten the hairspring in a manner that the balance will hang on the spring and neither the bottom of the tube, nor it's top will touch the limits. This is easy to check - try to lift or lower the balance along the string and You must see that it is possible and actually it hangs on the spring... As I understand, You didn't disassemble the movement and cleaned it in whole. No, this is wrong, as all the abrasive particles that got in the bearings with the dust and as wear product will stay there, and the old hardened oil can not be fully removed. The main springs can not be cleaned at all this way too. Sometimes such cleaning leads to stop of the movement again in about one month, and sometimes leads to very fast wear of the bearings.
