The 16570s have it, which is why my polar is the perfect travel watch. Don't need a $5000 rotating bezel
Of the Rolex GMT lineup my first choice would be amongst the Exp2, Batman or All Black, with a slight edge to the Explorer. I like the colours of the Batman but would be afraid that I might get tired of the colours, the All Black is more of an everyday watch but also looks too similar to the Sub, which leaves the Exp2 ticking more boxes. An upgraded movement, in particular a longer PR is what's holding me back. I've got time to wait and the watch fund to purchase it whenever "it" becomes available.
