First of all, thanks.
To answer your questions:
The caliber is 2049.
Thickness is 6.2 mm
The reference number is 15093BC.OO.A002CR.01
I understand the model is three years old but is still featured in AP's official web site. I have seen the watch with at least one AD that I know. There are altogether 5 variations. The latest versions are automatic. They are 41 mm in diameter and 6.7 mm in thickness, and do not have Roman indices.
Best
Sam
