How did I kill amplitude

[SiZi]

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.

As well as the case interfering with the results it could also be how the case is being held that's causing further problems.

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?

Was the hour hand touching the dial?

There should be a gap between the hour hand and the dial.

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