The result is a much cleaner design, which has much more of an instrument-watch feel to it than the original (the use of two buttons in the case flank to adjust a dual time zone complication makes a great deal of sense functionally but it’s always struck me as creating a bit of an aesthetic challenge, even in classics of the sub-genre like the Ulysse Nardin GMT ± Perpetual). The bezel now carries some fairly prominent knurling and it’s as easy to grasp and manipulate as you’d hope, as well as easier and more natural than successive presses on pushers, or unscrewing a crown to re-set the hour hand (the day/night indicator of the preceding model has been retained).

Of course neither of those systems is the end of the world either, but a world timer system in the lineup that’s aesthetically appealing, and meaningfully different, is a very nice thing for Oris to have. The system is actually somewhat reminiscent of the Vogard dual time zone complication, which was adopted by IWC for the Pilot’s Watch Timezoner Chronograph; that watch is both more complex and quite a bit more expensive than the Oris ($11,900 for the IWC vs. $3,600 for the Oris) albeit it comes with a chronograph (and has a very different aesthetic as well).
