Rolex Explorer II Polar References

The Rolex Explorer II Polar series spans across decades of watchmaking excellence, with each reference number representing significant progress in design and technology. The individual references track the development of one of Rolex's most beloved professional watches, harmonizing the brand's technological progress with its practical approach to style. From vintage designs to modern reinterpretations, each Explorer II Polar reference has contributed its share to solidifying the watch's enduring heritage.

Ref. 16570

Introduced in 1989, reference 16570 represents a refined evolution of the Explorer II line that remained in production for nearly two decades. This reference brought significant upgrades, including the caliber 3185 movement (later updated to 3186), a more balanced 40mm case profile, and improved luminous material for enhanced low-light visibility.

With its crisp white dial, sleek sword hands, and perfectly proportioned hour markers, the Rolex Explorer II 16570 Polar achieved a sophisticated balance between tool watch functionality and everyday wearability. Collectors appreciate this reference for its ideal dimensions and design that seamlessly bridges vintage and modern Explorer II aesthetics, representing what many consider the quintessential Explorer II expression.

Ref. 216570

2011 saw the Explorer II line undergo its largest redesign ever with the launch of reference 216570 as part of the brand's commemoration of the 40th anniversary of the collection. This reference is easily noticed by its larger 42mm case and the revival of the vintage orange "Freccione" 24-hour hand of the first Explorer II, both of which add to its strong presence on the wrist.

Equipped with the caliber 3187 movement featuring Paraflex shock absorbers and Rolex blue Parachrom hairspring, the Rolex Explorer II 216570 Polar offered enhanced resistance to magnetic fields and shocks. The white dial featured larger hour markers and hands filled with Chromalight luminescent material, emitting a distinctive blue glow in darkness while maintaining the signature aesthetic that made the Explorer II a favorite among collectors and adventurers alike.

Ref. 226570

Introduced in 2021 to celebrate the collection's 50th anniversary, reference 226570 represents the current iteration of the Explorer II. While maintaining the 42mm case diameter of its predecessor, this reference offers subtle refinements, including optimized proportions, slimmer lugs, and a wider bracelet that enhances both comfort and visual balance.

Powered by the new-generation caliber 3285 movement with Chronergy escapement, the Rolex Explorer II 226570 Polar features greater accuracy, power reserve, and anti-magnetism. The white dial continues to honor the tradition of unparalleled legibility with re-designed hands and hour markers proportioned perfectly to the size of the dial. Adhering to contemporary sophistication, the Explorer II Polar remains true to its tool-watch heritage, a hallmark feature for over five decades.

Ref. 16550

Reference 16550 holds a special place in collector circles as a transitional model produced for only a brief period between 1985 and 1989. This reference introduced several significant updates, including the first white "Polar" dial option in the Explorer II line, sapphire crystal, and the caliber 3085 movement with independent 12-hour hand adjustment.

What makes the Rolex Explorer II 16550 Polar particularly coveted among vintage enthusiasts is its unique "cream rail dial" phenomenon. Many white dials from this production period have developed a warm patina over time due to a manufacturing quirk, transforming from stark white to a rich cream color. Combined with its glossy dial surface and black-outlined Mercedes hands, this unintended aging has created one of the most distinctive and sought-after vintage Rolex aesthetics in the collector market.

Explorer II Polar Watch Specifications

The Rolex Explorer II Polar timepieces combine technological innovation with design elements specific to their expeditionary heritage. Built to meet the demands of extreme conditions while remaining accurate and dependable, these watches combine Rolex's signature balance of ruggedness and refined finishing. Every element of the Explorer II Polar demonstrates Rolex's commitment to creating watches every bit as effective in their performance and their attractiveness.

Materials

The Explorer II Polar is crafted from Oystersteel, a proprietary 904L stainless steel alloy that offers exceptional corrosion resistance and maintains its luster even in harsh environments. This specialized steel, developed specifically for Rolex's most demanding professional models, provides superior hardness while allowing for an exquisite polish that distinguishes Rolex watches from conventional stainless steel timepieces.

The Explorer II also features a scratch-resistant sapphire crystal with Rolex's Cyclops lens over the date window, enhancing readability while protecting the pristine white dial. The fixed 24-hour bezel is crafted from the same Oystersteel, with engraved numerals filled with black lacquer to ensure lasting legibility and resistance to fading or wear, maintaining the watch's functionality through decades of use.

Movement.

Early Explorer II Polar models utilized the caliber 1575 and 3085 movements, while the reference 16570 utilized the upgraded caliber 3185/3186 with hacking seconds and quickset date functions. These robust movements established the reliability that became the signature of the Explorer II series.

The current 226570 houses Rolex's state-of-the-art caliber 3285, featuring the innovative Chronergy escapement that increases energy efficiency by 15% while enhancing magnetic resistance. This self-winding mechanical movement delivers impressive accuracy with its variable-inertia balance wheel and blue Parachrom hairspring, maintaining precision in temperature variations and shocks. With approximately 70 hours of power reserve, the modern Explorer II movements represent the pinnacle of Rolex's in-house watchmaking capabilities.

Dial

The defining characteristic of the Explorer II Polar is its pristine white dial. The high-contrast black hour markers feature 18k white gold surrounds that prevent tarnishing, while the distinctive black hands with white gold edges create sharp definition against the white background.

Vintage reference 16550 examples are particularly desirable for their "cream rail dials," where the original white surface has developed a deep, warm patina over many decades. The dials have distinct parallel lines ("rails") between the minute marks, which are now considered to be highly desirable. Modern Explorer II Polar dials feature Rolex's Chromalight luminescent material, which emits a typical blue light in the dark, lasting significantly longer than traditional luminous compounds and still providing perfect legibility in all conditions.

Bracelet

The Explorer II Polar comes exclusively on Rolex's robust Oyster bracelet in matching Oystersteel, featuring solid links and end pieces that provide substantial durability for active wear. This three-piece link construction combines strength with comfort through its balanced weight distribution and ergonomic design.

Modern references incorporate Rolex's Easylink comfort extension system, allowing wearers to adjust the bracelet length by approximately 5mm without tools - ideal for accommodating wrist expansion in various conditions. The secure Oysterlock clasp prevents accidental opening while maintaining a streamlined profile that complements the watch's professional aesthetic. Throughout the Explorer II's evolution, bracelet improvements have enhanced both security and comfort while maintaining the distinctive Oyster design language.

Sizes

• Diameter: 40mm (Ref. 16550, 16570) or 42mm (Ref. 216570, 226570)
• Thickness: Approximately 12mm, varying slightly between references
• Lug to Lug: 47mm (40mm models) or 50mm (42mm models)
• Lug Width: 20mm, consistent across all Explorer II references

Water Resistance

The Explorer II Polar boasts a tremendous water resistance of 100 meters (330 feet), secured by Rolex's Twinlock patented crown system. This waterproofing is from the combination of precisely designed and engineered gaskets and screw-down crown that creates two watertight zones in the winding tube.

While not designed as a diving watch like the Submariner, the Explorer II's water resistance provides more than adequate protection for swimming, snorkeling, and exposure to extreme weather conditions. This capability reinforces the Explorer II's identity as a genuine tool watch designed for expedition use, where environmental challenges might include everything from desert dust to tropical humidity or arctic precipitation.

Rolex Explorer II Polar Price

The Rolex Explorer II Polar holds a prestigious position in the luxury watch market—a status reflected in its pricing structure. New Rolex Explorer II Polar models start at approximately $9,750 for the stainless steel version (Ref. 226570) at authorized dealers. However, due to high demand and limited availability, these watches often have waiting lists and can command significantly higher prices on the secondary market.

In the pre-owned market, Rolex Explorer II Polar prices vary based on factors such as the specific reference, condition, age, provenance, and overall market demand. Pre-owned versions on our website are categorized within the following price brackets:

• $7,000 to $10,000: This range typically includes older models in good condition, such as early Ref. 16570 watches. These pieces offer classic design and reliable functionality, making them excellent options for enthusiasts seeking the iconic Polar aesthetic at a more accessible price point.
• $10,000 to $15,000: Here, you'll find later versions of the Ref. 16570 in excellent condition, often accompanied by original box and papers, which add to their value. Some examples of the discontinued reference 216570 may also appear in this range due to their popularity and distinctive orange GMT hand.
• $15,000 to $20,000: This category encompasses sought-after discontinued models like the Ref. 216570 in pristine condition, as well as rare vintage pieces such as the Ref. 16550 with sought-after "cream rail" dials that have developed a desirable patina.
• Over $20,000: The most collectible Explorer II Polar watches fall in this premium category, including mint-condition vintage Ref. 16550 models with original documentation, rare transitional references, or special attributes that make them particularly desirable among collectors.

It's important to note that these price ranges are approximate and can fluctuate based on market conditions, the watch's specific characteristics, and overall scarcity. The enduring popularity of the Rolex Explorer II Polar often results in pre-owned prices exceeding original retail prices, particularly for discontinued models that are challenging to acquire.

When considering the purchase of a Rolex Explorer II Polar, thorough research and consultation with reputable dealers are essential. Authenticity verification is crucial, as counterfeit models can impact both investment value and collector interest.
