Could someone please explain something I must not be getting about these Autavia models such as the Viceroy ...

With the bezel marked as a tachymeter from 400 to 60 or so, what is the functional benefit of having it rotate?

I can imagine that you could align the triangle with the minute hand to see elapsed time movement, but it isn't directly readable from the bezel scale, is it?

I've seen other bezels that have decimal markings, but ... would one ever rotate the Tachy bezel?
