Yes I have the le petit prince BP, picture below .
It's an amazing watch and I think you will love it , I sure do. The lug siize on it is 22 mm and it tapers to 18mm. As for what you should get that's a tough one. I have a 372 also and it also is an amazing watch, clsssic and looks good with so many straps. I don't have a 673 or 389 , but also great watches that I'd be proud to have . I guess it's really what your preference is and what your current collection consists of . Here is the blue BP
