The 15202 wears bigger, too fragile to wear, too cumbersome to adjust time and date, and too scratch-prone. I got the watch last year and hardly wear it. But love to have it in my collection.
5711 was a revelation, initially not a hard hitting Nautilus compared to its other siblings especially the 5712 and 5980. Gained quite a cult status in the last 3-4 years and was glad to have it back in 2011.
Thanks for this poll. You can’t go with either model. For the IP, can’t really comment as I haven’t seen nor wear one.
Cheers!
