Rolex Explorer II Review: Rolex 16570 Polar White ‘v’ Black Dial

If you’re searching for a detailed Rolex Explorer II review, particularly of the now-discontinued reference 16570 – you’ve come to the right place. The Rolex Explorer II 16570 holds a special place in the brand’s history, combining classic tool-watch aesthetics with modern refinements.

This blog is comparing two classic 40mm Rolex Explorer 2 (16570) models – the very last versions ever produced. With both watches briefly in our hands at the same time, we had the perfect opportunity to explore their similarities, their differences, and what makes these final-edition watches so significant in the world of Rolex collecting.

Meet the Watches

The 2010 Rolex Explorer II – Polar White Dial

Our first watch is a 2010 Polar white dial 16570, sold in May 2012 after the model had already been discontinued. That makes this one of the very last Polar 16570s ever sold, a detail that collectors and enthusiasts will appreciate when reading any Rolex Explorer II review focusing on late-production models.

The 2010 Rolex Explorer II – Black Dial

Our second piece is also a 2010 16570, this time with the striking black dial. Again, this is one of the very last black-dial Explorer IIs made before Rolex transitioned to the updated 42mm 216570 model.

Having both versions together gave us the perfect chance to examine their late-series upgrades side by side. At the time of writing this blog, both watches are in stock, so check out our Rolex Brand page to see if either or both are still available.

What Makes These Final 16570 Models Special?

1. Engraved Rehaut (Inner Bezel Ring)

One of the biggest differences between these final 16570s and earlier versions and a common point in any modern Rolex Explorer II review is the engraved rehaut.

Peer through the sapphire crystal and you’ll see the ROLEX engraving along the inner bezel ring, with the watch’s serial number at 6 o’clock. Rolex introduced this around 2010, and only a small number of 16570s feature it.

Earlier models lack this detail, making these late-series Explorers more desirable.

2. The Upgraded 3186 Movement

Another major upgrade is the Calibre 3186 movement. Most 16570 models feature the 3185, but Rolex quietly fitted a limited number of final 16570s with the newer 3186, the same movement used in the GMT-Master II 16710.

Why collectors want the 3186:

• Smoother, more refined operation

• Updated Parachrom hairspring

• Less “wiggle” on the GMT hand

• Improved accuracy and reliability

• Rarity – only a small percentage of 16570s have it

Both of the watches in this comparison feature this prized upgrade, making them standout pieces in any Rolex Explorer II review discussing end-of-run models.
