Hello Everyone. Help needed please. 

2609HA. I've serviced the watch and oiled it, however, when dial side up, the watch really slows down to almost stopping. The only thing I can think of is to clean to balance jewels. Could this be the issue? Or could there be something else? Thanks for looking and help you can help!

Check the balance staff for wear such as roughness or chipped pivot or even broken. Make sure the jewel are good and the holes are round, not loose. check end stones, make sure they aren't loose. Is the impulse pin tight and smooth, check pallets. Make sure you use the correct oil and don't use to much, don't oil the pallet pivots.

Could be a dirty balance clock jewel or a bent balance staff pivot. Have you checked the hairspring isn't catching on anything when dial up.

    • I am puzzled by something a snipped out something from your image and what exactly disassemble tell us? my confusion is the symbol for FHF looks like image I have below year symbol as a star and righted this instant are not finding what that means? I suppose we could use the fingerprint system to verify it really is what it claimed to be. Size itself is really interesting there's almost no watches in that particular size. Then were missing details in the photograph above like diameter of movements to verify it really is the size and are missing the setting components.   went to the bestfit book looking at the symbols didn't see it. Look at the link below I did find it back to the bestfit book and yes it really is there https://reference.grail-watch.com/documents/history-of-ebauches-sa/ then bestfit book says lists the size as 10 1/2. one of the problems with vintage watches is finding parts yes a donor watch would be good.
    • Actually, this could be the issue. Drag from the module could be overcoming the cannon pinion. It was definitely not at the point that the driving wheel was loose on the cannon pinion, it took a little bit of effort to rotate it when applying the grease. Maybe I need to look again at applying oil to the pivots.    Yeah, it's very annoying. I don't want to give up on it, so back on with it over again until I catch a break. 
    • The sping is not pushing directly on the cap, but is pushing against the spindle. So, even if the usual black cap is replaced with the micrometer cap, the spindle is still pushed up.
    • But he tells that the micrometer cap doesn't screw into the spindle. How can the spring push the spindle up if there's nothing to grip? There is a screw visible on top of the micrometer cap so should it be able to screw into the spindle? I'm feeling really dumb now. Does anyone manufacture that cap as an aftermarket item? Might be worth investing. Ok so the spindle is different, now I get it.
    • I suppose? If it worked before and it doesn't work now I guess the question would be why does it not work now? That would come back to if you did not have the chronograph module on will it work or is the chronograph module sucking too much power out of the watch basically 99 usually when they go bad you can hold on the tube part and usually just spin the wheel because it has zero holding at all so usually when they go bad they go bad very bad. You should build hotel when you set the watch as to whether it seems to have any friction or not. I'm just wondering if the chronograph module is the problem.
