I currently have 4 Nautilus: - 5711/1R - 5712/R - 5726/1A - 5980/1A-019 white dal I want to expand my nautilus collection, and have two choices: 5711/1A blue dial and 5990. The 5711/1A is iconic and I can have more dial colours. With 5990, however, I can ... 

5711 /1A since you are missing a blue dial Nautilus.... 5990/1A since it is a reference you don't yet have, and also only have one thicker/sportier one in the 5980/1A. It really depends on what you enjoy wearing the most. Personally if it was me I would g... 

5711 is an simplification of the Genta's water proof design. The 3710 is a bit underrated and it can be found at reasonable prices. My 2 cents.

I don't understand what is all the rage about the 5711...It is not original nor is it technically a superior watch...

You seem to be a nautilus fan so in my opinion it would be a shame not to have an historical version. 3700 is quite expensive but 3710 nowadays has a very reasonable price. Best.

3711 should be nice, and I like the the feeling of being more hefty. But that would not serve the purpose of having different dial colour, as it quite matches that of 5726 and 5990 (if I get it later). If I get the 3711, I would definitely not get the 571... 

Anyway if the choice is only between 5711 and 5990 I would go for the first one. Best.

5711/1A because it is an iconic piece to hold in a Nautilus series and easier on the pocket book. Let us know your decision and we wait for your upcoming wrist shots ! Cheers, Gordon

...but I think you can do no wrong. Both great pieces. To my mind, the biggest obvious "gap" in your set is the iconic blue dial. A 5711/1A of course addresses that. If you are a traveler on the other hand, easy choice. Or, as suggested, rework the curren...
