I am not really crazy about Tourbillons. I like them when they are on the back side, but there are some notable exceptions from other brands such as Girard Perregaux, Ulysse Nardin and Jaeger Lecoultre, when the Tourbillon is not an addition which makes a terrible hold in the dial, but a part of the dial.
Breguet is part of these exceptions, in my opinion.
It is evident with such references as the 5335:

And the 5395:
And even when it makes a hole in the dial, it is superbly made...
Here the 5367 Classique Tourbillon Extra Thin:
Add the fact that Breguet has an indisputable legitimacy when it comes to Tourbillons...
Best,
Nicolas
