First of all, congratulations Puffy!
I love my 5617 too. Practically as much as my Nautilus Chrono, which is a big compliment to the Aquanaut.
However, Kari, I bought it both with the metal bracelet and the rubber strap. I have to say I wore the bracelet less than a week, and when I tried the rubber strap I have never gone back!
The bracelet is in the safebox ever since.
I believe the tropic strap is the perfect match for the 5167...
