Suprising, because the Semainier is not a complication we often see, indeed.
It is even strange, when you think 2 minutes about it, to conceive such a complication.
For what purpose?
I would answer " Why not? "!!!
The Date, the Day, the Month, ...Why not the week, indeed?
The tourbillon is the cherry on the cake ( or the cake under the cherry, if you consider it as more important than the semainier...: ) ), beautiful as often at Blancpain, nicely exposed on a dressy dial and an elegant case.
The pic: Gorgeous, as always.
Well, you put a smile on my face, today.
Thanks!
Best,
Nicolas
