Experience the craft of Rolex in the Explorer II (ref. 16570-0001), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 40 mm in diameter, with a thickness of 11 mm, defined by a round silhouette, paired with a fixed, 24 hour bezel. The caseback is closed, and the crystal is sapphire, delivering water resistance to 10000 meters. At a glance, the dial balances texture and clarity: a white tone, and mercedes hands. Among collectors, it is nicknamed "Polar". At its heart beats a proven engine: the 3185 caliber. Initial production year: 1989. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
