Dial spacer clearance? Does the day date align with the dial off? If so some thing is fouling. 

And this is listed as an Autavia... https://www.classicdriver.com/sites/default/files/styles/two_third_slider/public/watches_images/21801-07efe993f0e6e4256151008b401a329c_4.jpeg?1594988311

The technique in the video looks correct. I don't think you will find a better one. Maybe you have the wrong spring, or the jewel is sitting too high.

Try setting your timing machine to 18000 bph manually, then see what you get on the screen. If you have slo-mo on your phone, use that to check amplitude and frequency.

I'm working on this movement:  https://www.2209watchmovement.com/ I am at this point in trying to put the movement back together :    I'm really struggling to get the shock spring back in place.  I'm just not able to do it.  This guy makes it look simple.   I know that there are special tools to help with the removal and reseating of end jewel shock springs, e.g. diashock Is there a tool that someone would recommend for this movement or similar Russian movements? I've googled like mad and the antishock type that most closely resembles this movement's is called the "Brac Dip Resomatic" Does anyone know of a tool that would make this task simpler? If not, is there a video that demonstrates an effective technique for dealing with this kind of shock spring? Thanks,
