42mm Maxi case vs 40mm 16570
The 216570 is 42mm with broad Maxi lugs; a 40mm case cannot be a 216570. This is the clearest 16570-vs-216570 differentiator.

Early 24h-hand alignment service
Some early 216570 examples had the orange 24h hand slightly misaligned and were corrected by Rolex service; a correctly aligned hand is expected on serviced/later pieces.
