5960P, because it is cool to have a manual Wind Chrono movement and an automatic Chrono movement from the same brand. I like this idea.
Ruthenium because it is damn captivating. While you more often see black or blue dials, the ruthenium is top class.
Now, your title suggests me another way... Why not getting another extra fine Chronograph? A JLC Duometre, for example. Not only a fine movement and Watch, but an original one, with its dual Wind concept.
What a pair it would be with your 5070G!
Best,
Nicolas
