Iwc ingenieur mission earth winding

Hello Forum,

I have a question, I recently bought a used Ingy, Mission Earth, and I encounter a potential winding  problem. When I set the crown in position 1, and I want to manually wind the watch, after a few turns, the crown skrews itself down. It does wind up the watch, but I can’t turn it +\- 30 times. Only 5/6 turns. I am not pressing the crown.

My aquatimer does not have this “problem”. I this just how this movement works? Watch does run great.

Thank for reading and I am looking forward to your input.

Gr, Jeroen
