Rolex 3185

Probable

The GMT-Master II and Explorer II caliber that succeeded the 3085. Its replacement by the 3186 happened partway through the production of both the 16710 and the 16570, so those references may correctly carry either — which is exactly why the catalog records both as factory-correct for them rather than picking one.
