These 2 are very different: The 5712 is a more chic sport, while the 5980 is a sport sport chic.
The feeling is not the same, the 5980 looking bigger on the wrist, witjh more presence.
The 5980 is the extrem expression of a sporty Nautilus.
I waved a long time between these 2, and first got the 5712.
If I had to get another Nautilus in my collection, I would now hesitate between the Vintage, which is a killer, and the 5980.
I got tired of the moonphase you always have to set, on the 5712.
Cool pair, nonetheless.
All the best, my friend.

5712 is not good for a dip in the pool?
that changes my game...
Hope all is well my friend!
So got both of them.
