For the several reasons :
1- The simplicity of the dial and the superb finishing that will surely make it a timeless clasic beauty.
2- The enamel dial, that gives depth to the purity of the dial... And the Roman numbers with the "1/2 rail" connecting them. Might seem like a detail, but i think it breaks the austerity that sometimes comes with perfection

3- The small seconds gives a kind a nice dynamic to the dial.. And of course the blue hands.... Mmmmm, those blue hands feel like a fresh breeze from Glashutte

4- Last but not least, the famous chain-and-fusee principal, that reminds us real beauty is underneath. Gives it a romantic touch also by hinting to the genius of DaVinci, the control to keep an effective torque across the entire power reserve. Not only ingenious, but impressive how in such a small space, so much engineering fits so perfectly. Thats a complication that has a real impact on accurancy.
5- If only the back of the watch was completly transparent, that would be a 20/20... 19.5/20 makes it "human"... and hoping for the something in the futur that will put more in evidence that chain-and-fusee
