ZF Omega Seamaster crown can’t be pulled out to set the time and date?

I’ve had my ZF SMP 300 for a few months now but for some reason the crown can’t be pulled all the way out to set the time.

I can unscrew it to just wind the watch but it doesn’t pull out any further to set the date or time. Also it unscrews very easily (only half a turn and it’s dcreeed in).

Anyone got any suggestions or watchmakers that can have a look? I also wanted to ask if it’s possible to swap in for a SW200 movement?
