dear anaroku. Like you, your 3970P second version is my favorite here. And I would even say “by far” because the silver dial (and the leaf hands and rectangular indexes) makes it much more appealing to me than the black one. More “natural” and “friendly”, more understated and classic. There’s a severity and a desire to impress about the black dial which appeals to me far less. Just my personal taste of course.
Best, Emmanuel
