Great review, not in the market myself but love the classic Pepsi scheme.
One question David, you state that the simplest way to set a second timezone on the GMT hand is when the main minute hand is on the hour. Why is that? Is it because the GMT hand complication is 'smooth' and doesn't jump in hour increments when setting? That's quite a compromise if true.
I don't think I could live with this 'reverse-GMT' movement. I like the main handset to be the time where I am located and the GMT hand to be set to 'home'. Rolex's GMT movement allows the main hour hand to jump forwards and backwards while maintaining the correct relative position between hour marks.
