Peter,

Depends on which movement it is, the ESA 536.121 movements have a lever of such, with a small circular indentation upon it, when the crown is unscrewed and in the non date/time setting postition, just press the indentation down with a sharp object gently, stem should come out easily enough :)

Best,

James.
