Explorer 16570 'Polar'

Introducing the Rolex Explorer II, a remarkable watch that emerged in 1971 but often remains underappreciated. This twristwatch was specially crafted for adventurous cave explorers, setting it apart as a unique companion rather than a direct successor to the original Explorer. In 1989, Rolex introduced the Explorer reference 16570, which continued to captivate watch enthusiasts until 2011. While bearing similarities to its predecessor, this model boasted some noteworthy improvements.

The updated 16570 housed an enhanced mechanism, delivering improved accuracy for precise timekeeping. It also featured a convenient quick-setting hour hand, making it easier to adjust the time when traveling across different time zones. The white-dial version caught attention with its striking black outlines around the hour markers, earning it the affectionate nickname "Polar Explorer" for its appealing appearance.

Over time, the luminescent parts of the watch evolved. Models produced before 1997 utilized Tritium for the glow-in-the-dark components, which aged gracefully with a charming yellowish patina. After 1997, Rolex switched to Luminova, a luminescent material that maintains its brightness without any color changes.
