Rolex Explorer II 16570
The Rolex Explorer II 16570 is a classic Rolex professional tool watch recognized for its 40 mm Oyster case, fixed 24-hour graduated bezel, additional 24-hour hand and practical second-time-zone functionality. Produced from approximately 1989 until 2011, reference 16570 occupies an important position in the history of the Explorer II.
The Explorer II was originally introduced by Rolex in 1971 for explorers, speleologists and people working in environments where distinguishing day from night could be difficult. Its distinctive 24-hour hand and fixed 24-hour bezel became defining features of the collection. Explore the history of the Rolex Explorer II on the official Rolex website.
For collectors searching for a Rolex Explorer II 16570, this reference offers the classic 40 mm proportions, stainless-steel construction, Oyster bracelet and dual-time functionality associated with the five-digit-generation Explorer II.
Rolex Explorer II 16570 Design
The Rolex Explorer II 16570 has a distinctive tool-watch design built around functionality and legibility.
Its fixed 24-hour bezel surrounds the dial, while the additional 24-hour hand makes it possible to distinguish a second time zone and, depending on how the watch is used, distinguish daytime from nighttime hours.
Unlike the GMT-Master II, which uses a rotating 24-hour bezel, the Explorer II 16570 uses a fixed 24-hour bezel. This is one of the characteristics that gives the Explorer II its distinctive identity.
The 40 mm case also gives the 16570 a different wrist presence from the later 42 mm Explorer II generations.
Collectors looking for other luxury sports watches can explore the LuxeChronos luxury watches collection for additional Rolex and Swiss luxury-watch models.
Rolex Explorer II 16570 40mm Case
The Rolex Explorer II 16570 is known for its 40 mm stainless-steel case.
Examples of the reference are documented with a 40 mm case, sapphire crystal, fixed 24-hour bezel and 100-metre water resistance.
The 40 mm format became an important characteristic of the 16570 generation and differentiates it from the later 42 mm Explorer II 216570 and 226570 references.
The case is designed around Rolex’s Oyster architecture, with a screw-down case back and screw-down crown.
When purchasing a pre-owned Rolex Explorer II 16570, the condition of the case is particularly important. Collectors should examine the condition of the lugs, bezel, crown, case back and bracelet, as polishing and wear can affect the appearance of an older watch.
Rolex Explorer II 16570 24-Hour Bezel
The fixed 24-hour bezel is one of the most recognizable elements of the Rolex Explorer II 16570.
The additional hand makes one complete rotation every 24 hours and points toward the 24-hour graduation on the bezel.
This design originated with the first Explorer II in 1971. Rolex explains that the 24-hour indication was developed to help users distinguish daytime from nighttime in environments where natural light could not easily provide that information. Read Rolex’s official explanation of the Explorer II 24-hour display.
The fixed bezel also contributes to the Explorer II’s unmistakable appearance.
Rolex Explorer II 16570 White Dial
One of the most recognizable configurations of the Rolex Explorer II 16570 is the white dial, commonly referred to by collectors as the “Polar” configuration.
The white dial creates strong contrast with the black-bordered hour markers and red 24-hour hand.
Examples of the 16570 were offered with both white and black dials. Auction and specialist records document both configurations with the 40 mm case and Calibre 3185.
The white-dial Explorer II 16570 has become particularly recognizable because of its contrast with the black hour markers and steel 24-hour bezel.
If your LuxeChronos product photograph shows the white-dial version, use “Rolex Explorer II 16570 Polar” as a secondary SEO keyword rather than incorrectly treating “Polar” as the official model name.
Rolex Explorer II 16570 Black Dial
The Rolex Explorer II 16570 black dial provides an alternative appearance to the better-known white-dial configuration.
The black dial emphasizes the tool-watch character of the Explorer II and creates a more understated appearance.
Specialist and auction records document black-dial 16570 examples using Calibre 3185, stainless-steel cases and Oyster bracelets.
For LuxeChronos, the exact dial configuration should be included in the product title if the watch is specifically black or white.
For example:
Rolex Explorer II 16570 Black Dial
or
Rolex Explorer II 16570 White Dial Polar
This creates a more precise product page and improves long-tail search targeting.
Rolex Explorer II 16570 Calibre 3185
The majority of the Rolex Explorer II 16570 production used Rolex Calibre 3185.
The automatic mechanical movement provides the watch with its timekeeping and GMT/second-time-zone functionality.
Reference guides document the 16570 as initially using Calibre 3185, with later examples transitioning to Calibre 3186.
Because the reference remained in production for many years, movement details can vary according to production period.
For that reason, a LuxeChronos product listing should identify the actual movement where it has been verified rather than automatically stating that every 16570 contains Calibre 3185.
Rolex Explorer II 16570 Calibre 3186
Later examples of the Rolex Explorer II 16570 transitioned from Calibre 3185 to Calibre 3186.
This is an important detail for collectors because the 16570 is a long-running reference with multiple production-era changes.
Reference guides place the Calibre 3186 transition in the later years of the 16570’s production, alongside other changes such as the rehaut engraving.
Therefore, if the specific LuxeChronos watch has a verified Calibre 3186 movement, the product title and description can target:
Rolex Explorer II 16570 Calibre 3186
rather than simply using the generic 16570 keyword.
Rolex Explorer II 16570 Sapphire Crystal
The Rolex Explorer II 16570 uses scratch-resistant sapphire crystal.
The crystal protects the dial while maintaining the legibility expected from a professional Rolex sports watch.
A Cyclops lens magnifies the date display at 3 o’clock, another recognizable Rolex feature found on the Explorer II. Contemporary Rolex documentation describes the Explorer II’s sapphire crystal and Cyclops date magnification as part of its Oyster architecture.
On a pre-owned 16570, the condition of the sapphire crystal should be checked carefully for scratches, chips or damage.
Rolex Explorer II 16570 Date Display
The Explorer II 16570 includes a date display positioned at 3 o’clock.
The Cyclops lens magnifies the date aperture, making the date easier to read.
This practical combination of date functionality and second-time-zone capability contributes to the Explorer II’s reputation as a functional everyday tool watch.
When creating a product listing, the date function should be included in the specifications because it is one of the defining practical features of the reference.
Rolex Explorer II 16570 Oyster Bracelet
The Rolex Explorer II 16570 was paired with the Rolex Oyster bracelet.
The three-piece-link Oyster design complements the tool-watch character of the Explorer II and provides a robust bracelet configuration.
For a pre-owned 16570, the bracelet condition should be documented carefully.
Important details can include:
- Bracelet reference
- Clasp condition
- Stretch
- End links
- Number of links
- Replacement components
- Originality
These details are particularly relevant for vintage and discontinued Rolex watches.
Rolex Explorer II 16570 Water Resistance
The Rolex Explorer II 16570 is generally documented with 100 metres of water resistance.
However, with a decades-old watch, water resistance should not be assumed solely from the original specification.
For a pre-owned watch, the current condition of the gaskets, crown, crystal and case should be considered, and water-resistance testing should be performed by a qualified watchmaker before the watch is used around water.
This is particularly important when selling a vintage or discontinued Rolex.
Rolex Explorer II 16570 Production History
The Rolex Explorer II 16570 was introduced in approximately 1989 as the successor to the 16550 and remained in production for more than two decades. It was eventually replaced by the 42 mm Explorer II 216570 in 2011.
This makes the 16570 an important transitional reference between earlier Explorer II designs and the larger modern generation.
The reference also went through several production changes during its lifetime.
Collectors may encounter differences in:
- Luminous material
- Dial printing
- Rehaut treatment
- Bracelet construction
- Movement
- Case details
This means the production period should be considered when evaluating a particular Rolex Explorer II 16570.
Rolex Explorer II 16570 Tritium, LumiNova and Super-LumiNova
One interesting aspect of the 16570 is the evolution of its luminous material.
Earlier examples used tritium, followed by transitional LumiNova examples and later Super-LumiNova examples.
Specialist references identify different dial markings corresponding to these production eras.
This can be particularly relevant to collectors because the luminous material can help establish the production era of an individual watch.
When selling a vintage or collectible 16570, LuxeChronos should therefore avoid making a generic statement about lume and instead identify the actual dial and production characteristics where they have been verified.
Rolex Explorer II 16570 vs Modern Explorer II
The Rolex Explorer II 16570 differs significantly from the current Explorer II.
The 16570 uses the classic 40 mm case, whereas the current Rolex Explorer II reference 226570 uses a 42 mm Oystersteel case and Calibre 3285. Rolex’s current specifications list the 226570 at 42 mm with a fixed 24-hour bezel, 100-metre water resistance and approximately 70 hours of power reserve. See the current official Rolex Explorer II specifications.
The distinction is important when writing product descriptions.
A Rolex Explorer II 16570 should not be described as having the current 226570’s 42 mm case or Calibre 3285.
Keeping these specifications separate improves both product accuracy and SEO relevance.

Rolex Explorer II 16570 for Collectors
The Rolex Explorer II 16570 occupies an interesting position in Rolex collecting.
It retains the practical character of the original Explorer II while introducing the modern 40 mm case and independent GMT functionality that defined later generations.
Because the reference was produced over such a long period, individual watches can vary considerably.
A collector evaluating a particular 16570 should consider:
- Production year
- Serial information
- Dial configuration

Providing the exact reference helps narrow the search considerably.
Rolex Explorer II 16570 Authenticity
Authenticity is particularly important when purchasing a discontinued Rolex.
The Rolex Explorer II 16570 has existed in multiple production configurations, so authentication should consider the watch as a complete object rather than relying on a single visual characteristic.
The reference, serial information, dial, hands, bezel, case, movement, bracelet and documentation should all be consistent with the claimed watch.
Rolex explains that its official retailers have the necessary expertise, equipment and skills to authenticate and maintain Rolex watches. See Rolex’s official guidance on retailers and servicing.
For a LuxeChronos listing, never claim that a particular watch is authentic unless the individual watch has actually been verified.
Customers with questions about a particular listing can contact LuxeChronos.
Rolex Explorer II 16570 Price
The price of a Rolex Explorer II 16570 varies according to the individual watch.
Important pricing factors can include:
- Production year
- Dial configuration
- Lume type
- Calibre
- Condition
- Originality
- Bracelet condition
- Box and papers
- Service history
- Provenance
For example, a well-preserved early 16570 with original components can differ substantially from a later example with replacement parts or extensive polishing.
For LuxeChronos, the regular price and sale price should therefore be based on the exact watch being offered, rather than using a generic price for every 16570.
Rolex Explorer II 16570 White Dial vs Black Dial
The white and black dial versions offer different visual presentations.
The white-dial Rolex Explorer II 16570 provides a high-contrast appearance and is commonly associated with the “Polar” nickname used by collectors.
The black-dial Rolex Explorer II 16570 has a darker, more understated appearance and emphasizes the watch’s tool-watch character.
Both configurations belong to reference 16570, so the correct dial should be specified in the LuxeChronos product title and image metadata.
Rolex Explorer II 16570: A Classic Five-Digit Rolex
The Rolex Explorer II 16570 represents an important chapter in the development of Rolex professional watches.
Its 40 mm case, fixed 24-hour bezel, additional 24-hour hand, date display, Oyster bracelet and automatic GMT functionality combine to create a highly recognizable Explorer II configuration.
The reference’s long production history also makes it particularly interesting for collectors who want to explore differences between early and later examples.
The later 42 mm Explorer II generation and current 226570 are separate references with different case dimensions and movements.
