Well, the TR 900 is quite hard to find, as it seems that many of the circa 1100 died; and that all those who pay a cult to this watch may evaluate their surviving number to around 100, 150?
Thee Pakistani is much rarer, by far, as well as the AM.
But the Cult, the icon is the TR 900.
I would also rate very high one of the first military Milspecs.
And a " Bronze " Milspec, too.
Best,
