How many movements do you have now? 

we have approx. 480 of the 405 based caliber movements. From the 405 itself to the A. Lincoln a 21 jewel version with a fine pinstripe.  We have also many of the movements collected for our 2nd and 3rd generations of this series. 

How long will you be able to make these watches before the movement supply is all used up given that they are 100yrs old and not being manufactured anymore?

I have a pretty good supply of them and  do not intend to slow down on acquisition once your consumer demand is up and running.  There were ~400,000 of these made over a 15 yr period and most are hiding in grandpa's grawer and as things are passed down they find their way into my supply channels.
