It will be on the 5980...
To me, the 5980 is the ultimate expression of the Naulilus, its sporty spirit.
With Time passing, I was not very comfortable with the moonphase, as I had to set it every time I gave this watch some wrist time.
But the 5711 bis another option, I must admit.
BUT, I already own the RO jumbo.
Best,
Nicolas
