...as the very happy owner of the 2015 salmon 3940.....see other thread on this where I (attempt to) analyse that piece: 3940 elements, 5140 elements and some completely unique elements.
So this is a 3 way choice: 3940, 5140, or 3940 of 2015 (apparently a gimmick, for some, though I think that is a commentary on PP's perceived integrity rather than the piece itself).
For what it's worth, I too love the 3940 first series dial. Problem is that with some of those you have to "put up with" a solid back, hiding a really special movement. So, I guess we'll also have to add the 3941 into the discussion too!
