Hi everyone !
I need your advice mates :
I have bought a Flieger B (cal 2824-2) in mid 2012.
In my memory, since the beginning the crown was a bit hard to turn (a bit, not a lot) and not everytime, but some told me that it may happens on calibers 2824 and that was not serious.
Now I am back from a 4 months deployment, and I have let my mecanical watches at home and none have touched or moved it.
The watch seems to run OK even ifI haven't check its precision. The crown seems to do its job.
I just looked at the see-though glass, and see a deposit of some "metallic dust" that gather inside against the glass (at the crown side).
