Can I Keep The Tourbillon "Thing" Going?

As I am posting this, a thought occurs to me.  The range of Blancpain Tourbillons is really extraordinary.  I haven't done a count of all of the different models, offering different complications alongside the tourbillon itself, but the number would be large. 

This watch is the Tourbillon Semainier.  The featured additional complication for the Semainier is the week of the year complication.  There is actually a bit of a story to be told here concerning the number of possible weeks in the year.  We were all taught in school that the year has 52 weeks.  Good convenient number to remember, 52.  Trouble is that number is really not correct.  In many years there are actually 53 weeks.  If you have Microsoft Outlook you can check that because the software will display the week number.  Turns out every 4 or 5 years or so a 53 week year comes along.  So appropriately the Semainier allows for 53 week years.  Oddly there are a bunch of watches from famous brands that offer week of the year indications.  And they all only go up to 52.  So basically on those 53 week years, those watches show "Week 1" in December.  Frankly, that's bad form. 

A couple of other details on this watch. It's diameter is 40mm, whereas until now the Leman Tourbillons were 38mm.  And the watch has both a large date and power reserve indications.
