What is the trick to get the clock reset knob off a 1970 tack clock combo . Thanks

Small flat head jewelers size in the middle

Be ULTRA careful with those! That tiny little metal rod behind that knob is super-duper easy to break and expensive to repair/replace. And yes, there's a tiny little flat-head screw in the center of the knob.
