And to make it short, yes, it is.
I can understand that... Not my favourite among the 3, when launched in 2006, but now, it is.
Maybe the 5712 looks mre refined than the 5980, but this last one is more powerful, and sums quite well the spirit of the Nautilus: Elegance and Sportivity.
If I had to get another Nautilus in my collection, I would have hard time choosing between the Nautilus Vintage ( 3700 ) and this 5980.
Best,
Nicolas.
