A chef once joked to me that the secret ingredient to a fillet mignon was an extra 20 quid. It would be easy, albeit a little churlish, to suggest the tourbillon movement could be subjected to a similar observation, but with a punchline of one or two extra zeros. Perhaps even an entire comma.
Tourbillon watches generally start at around £20,000 and quickly head off into the land of six or even seven figures. Bentley once offered a self-winding tourbillon clock on the dashboard of its Bentayga SUV for £150,000. That was the price of the clock, by the way, not the car.
