Tricky, If i'm not mistaken this is one of those chinese tourbillon movements. I can find no other information about it, parts don't appear to be sold anywhere obvious. 

I'd suggest you probably have two avenues.

1. Get a stem extension. There's really not a lot of thread left on the tip of that stem, so it's not ideal, but it might work. Stem extensions can be obtained by virtually any watch part supplier. 

2. Cousin's has a page of chinese stems with detailed information about the various dimensions, you might be able to take measurements with a vernier guage, and it might match up with one of the stems offered there.

Just for the record, Chinese (Seagull) only make one true tourbillon caliber, it costs like $3,000 but nobody buys it.

The others are "open heart" movement where the balance is visible from the dial side, not sure who these can actually impress.

Right, of course. they're meant to pass for tourbillons but it is a bit insulting to tourbillons to call them that.

Brilliant advice many thanks

If you choose to use a stem extender, you best solder the joint too, since not much thread is left. 

Make sure to clean and rinse the stem, as you instal the extender, you be left with a groove between the two pieces,  solder it, to strengthen the joint.

Many thanks for all of the help with this question. Stem extension did the trick brilliantly. Completed and fixed with some thread adhesive and it appears to be holding well.
