Just been looking at a piece on a watch from a Swiss maker, it’s being produced on a sort of crowd-funded system, in that each watch made is custom made to order, there won’t be any available to buy outside of the order system. Not cheap at 6,990chf, £5854, but what really sets it apart is the fact it’s a chronometer-grade tourbillon movement!

A tourbillon separates the main movement from the rest of the watch workings, more or less making it immune to the effects of the watch being moved around, and they’re usually incredibly expensive, the TAG tourbillon is £15,000.
I’m not usually a fan of skeletonised movements, but if I had the means to buy one of those, I’d grab the chance.

There are really cheap ‘tourbillon’ watches on Amazon, I have doubts as to how genuine their movements are, a genuine tourbillon is basically a showcase of watchmaking skill, hence the prices.
