The Rolex Explorer 2 II 16570 Polar is a rare watch with a random serial number from 2011, featuring a stainless steel bracelet, “polar” white with round indexes, and a 40mm stainless steel case. This sporty wristwatch has a 24-hour dial, a mechanical automatic movement, and comes with its original box, warranty card and booklet. I have a validated 3186 movement letter from an accredited Rolex watchmaker. I have also added a Steel Reef 904L comfort extension link upgrade. Please note that the green hang tag has been scratched off.
