Lorenzo,

Thank you for this very interesting and useful side-by-side comparison!

Without discussing the pros and cons of every difference between the two, there is one thing I had never noticed before: it looks as if the subdials of the 7753 have a slightly larger diameter than the ones of the 3647. After overlaying both watches in Photoshop, it actually seems to be the case.

My personal preference is the 3647, which for me embodies the true sense of reduction and elegance: less is more. I even like it more than the 2447.

As a small side note regarding your fantastic watches, I haven't seen a silver chrono second hand on a 3647 N so far, I always thought it should be white.

Robert
