They are all very nice especially the Datograph Perpetual but for me, what moved me at first glace of all the new releases and stll does is this piece of art.
Although I can never buy it for my own wearing pleasure, to me, the choice of the blue mop, the setting of the diamonds, choice of strap comes together in a very very tasteful and beautiful manner. One that catches your eye but in a subtle, not overly loud manner and most importantly for me, in a manner that doesn't tire easily.
Sure its not the most complicated when compared to the Dato Perpetual but this to me, can stand as one of the great testaments to Lange's class and finish.
Just my opinion of course.
