From Basel 2011

A snapshot of how the new Explorer II 216570 evolved... First was the 1655 (picture borrowed from www.hodinkee.com):

Then came the 16570 (from my private collection):

The new Explorer II 216570 was launched at Basel 2011:

With a case diameter of 42mm, the 216570 was an instant hit as collectors longed for a larger case from the standard 40mm. In both the white and black dial configurations, the striking orange GMT hand and wordings stand out distinctively from the dial. With the trademark brushed oyster bracelet, the black dial 216570 is a sporty watch as compared to the more elegant white dial 216570.
