It looses the Calatrava Cross for an ugly " TAG " shaped one...
Another point I agree with you is that I too would have preferred to see the dial of the 5131 on the 5110...
These Patek WTs have no cotender in my book. They are THE WT, by excellence.
Well, at the exception of a certain GP WWT TC with its sublime enamel dial and the Tourbillon with 3 Gold Bridges, maybe?
Best,
Nicolas
