Because of marketing and what it is. The backstory of the Submariner is so much more interesting that most want to be part of that saga. From Comex divers, deepsea explorers, the military, fictional spies. The submariner is everywhere whereas the polaris is just known to a handful of watch enthusiasts.
I personally would not choose a JLC diver as my next high end diver purchase ( if achievable) as that slot will be filled by the Blancpain Fifty Fathoms ( which has a better backstory akso) or even another Rolex - Yacht master 42 titanium in the metal is gorgeous in that tool watch sort of way.
During the covid era that happened. These days not so much. But new Tudors trickle into ADs. So first come first serve if the regulars don't place bookings for them right away. I did that when the Pelagos 39 was launched and was first or second at the AD. Then no P39 came into the store for about two months. TheP39 still fly out of the store pretty fast over here in Kuala Lumpur.
