And wonderful insights. For some reason, the RL Tourbillon speaks to me the most. And you perfectly summarize it, in the sense that it covers broadly the three elements...accuracy, stability and kinetic. I haven't conceptualized it like that before.
But realistically for me, the L1 Tourbillon is more within my reach. I have zeroed the next Lange down to Dato QP, DS or the L1 tourby...and now saving up slowly but surely. This post might have swung it the Tourby way!!
Best,
