The 3970EJ is a legitimately impressive perpetual calendar chrono that does everything right on paper-the movement is a technical masterpiece and it wears surprisingly well for something this complicated. That said, at this price point you're really paying for the name and the complications rather than getting something that outperforms a simpler Patek in actual daily use, which keeps it from being a slam dunk for me. Still a grail watch for the right collector, just not quite the no-brainer it's hyped up to be.
