 The ability to make synthetic jewels must be post WWII technology.  Were pre-WWII movements utilizing naturally occuring sapphires?  Were these pivot points hand made?  .... no wonder 17 jeweled movements were 'high class' :-)

I notice a number of the cheaper movements have few jewels if any.  I take it these are using the mineral glass?  Or is it metal on metal?
