I just put back a Raketa 2609.ha. All went well and the amplitude was super strong between 290-310. Then I put the dial on and hands on and now the amplitude has dropped to 170-180. Is it possible that I pressed the dial on too hard while screwing down and that might have put pressure on the hour wheel and so it’s dropping altitude? Is this something you have experienced? What else could it be from my putting back the hands on, dial back on, and movement into the case that might be causing such a drop in amplitude. 

Thanks for the help, as always!

Before taking everything out again, varify that the amplitude is actually that low, the case might be interfering with readings.

Give it a full wind, then work backwards. Remove the second hand and check amplitude. Remove minute hand and check. Remove hour hand and check.... until you are down to bare bones or when amplitude goes back to 290-310.

The seconds or minute hand along did not change much but when I took off the hour hand the amplitude shot up 40 degrees!

Is this an indication of the hands being too tight? Or what?

Not tight on their arbors but maybe the hour hand tube rubbing on the dial hole.

    • If at all possible, find a service guide for the automatic movements your work on, because the lubrication procedures may have different requirements or rely on oils you would not use in a manual wind train (in addition to the braking grease you mentioned). Some autos like older Seikos do not have a manual wind option, so the procedure of letting down the mainspring without being able to use the crown may require a screwdriver in the ratchet wheel screw and great care. Do you have an auto movement you were planning to start with?
    • I am an amateur, so there's that. I do not get fixated on amplitude, lift angles, and beat error. However, 4.8ms would bug me if it were my watch. But you must judge your own skills to appreciate the possibility of going backward. I suggest, that you button it up let your friend enjoy the watch for now. As your skills progress, come back to it and correct it. I assume that this watch has a fixed hairspring pin. Some modern watches have an adjustable pin along with adjustable regulator. These are trivial to get in beat. I own a valjoux 726 my dad gave me on my 18th birthday (a looooong time ago). I broke the ratchet wheel with an aggressive wind 4 yrs ago. I have been waiting for my skills to progress before doing a service. I am close. Your advice is well placed and I will apply it.
    • I didn’t find any anomaly to the left of the red mark…reflection? this is the balance in its pivot in the inverted assembly. i can’t see any obvious kinks  and the spring is flat as far as I can see. Either the stud screw is missing, or it’s glued in… I don’t know. I’m loathe to fiddle with it. Any further insights? Thanks!
    • Update!  I've dismantled it, cleaned all the glue off, and rebuilt and lubricated the base movement. I'll leave the chrono part for another day. It's running well - great amplitude and keeping time, but it's got a beat error of 4.8ms.    How important is it to correct this? I'm worried that the potential for making things worse having to take the hairspring off and on repeatedly to adjust this. Would anyone here accept it at that?
    • Since I've been banned from the previous discussion, apparently my language was inappropriate...for small boys. I will start another thread and act in a more decent manner for the girls and ladies of the group.  Please what will happen if the forum can't be managed by the administrator, are there provisions in place to preserve the achived member's questions and answers over the years. Please if I may ask these important questions that are important to the members please.
