MING has pretty much openly admitted that they're doing very little themselves and nearly everything is done externally. The value add that MING provides is a superlative design that's really a great paradox - it's classic and easily accepted by just about anyone - and yet it's gone modern flourishes too and cool modern touches. It's like that new BMW 7 series with a lot of modern technology features, but it's still appealing to those who want that familiar old world luxury. Another value add that MING does here, is that it's not limited to one manufacturer - they can go anywhere for the best solutions to achieve their design purity. They'll buy movements from Schwarz Etienne, movements from Valjoux, or others - whichever one they think is the best solution for that specific project. Then they'll customize those movements - which balloons the cost tremendously with special finishing, black-out treatments, etc. to make it more in the spirit of MING. Just like how BMW will go to different manufacturers to source gearboxes. For US Market cars, BMW has bought transmissions from ZF, Aisin (a Toyota supplier, probably also a Toyota subsidiary), and probably other suppliers I can't recall - finding the best pairing and the best solution for their product.
