Hi,
As others have said, that ceiling was broken a long time ago. Ignoring Chinese made tourbillons, we have Horage and BA1110D Swiss made tourbillons at less than £5000. Finishing will be industrial etc but it is Swiss made and I find the BA111OD design quite nice.

I guess there must be a market for these for those who desire a tourbillon and is able to pay at the a mid to high 4 figure bracket but don’t want the quality that is offered at the sub-£1000 level. Let’s face it, outside of WPS and WIS, £5000 would be considered a fairly high price for a watch!
