Horological Meandering

Bidded this Porsche Design PTR 6613 Titanium from auction on the weekend, haven't seen a quad registers on the dial, and the calendar date can be moved forward or backward to adjust.

Don't leave us hanging.
Bid at auction is one thing.
Successful bid is another.
Is it yours?!?

I have not followed Porche Design enough to know all models. This one is very sleek with clear indicators. What is the model?

Yes, I bidded this from the auction.

The movement is a modified Valjoux 7750. Alfred Rochat is the movement maker, I have one with a sterile dial. They make a great racing tool watch.
