The Rolex Explorer II Ref. 216570 is a discontinued 42 mm Oystersteel watch with a fixed 24-hour bezel, orange 24-hour hand and calibre 3187. Its independently adjustable local hour hand makes time-zone changes practical while preserving a reference-time display. In 2026, it is a pre-owned purchase, so assess the specific watch, its provenance and seller protections rather than relying on a model-wide price claim.
The 216570’s appeal lies in its distinctive design, legibility and traveller-style GMT function. Its main trade-offs are its substantial wrist presence, approximately 48-hour power reserve and the extra diligence needed when buying a discontinued watch.

What is the Rolex Explorer II Ref. 216570?
Rolex introduced the 216570 generation in 2011, and a June 2026 specialist dealer guide gives its production period as 2011–2021. The successor is the Ref. 226570. The 216570 was offered with white and black dials.

The model’s defining arrangement is a fixed steel 24-hour bezel and a dedicated 24-hour hand. Rolex describes the hand as making one circuit of the dial in 24 hours and pointing to the bezel’s fixed graduations. The 216570 combines this display with a large case and a prominent orange hand, giving it a distinctive instrument-watch character.
The fixed bezel is not a rotating elapsed-time bezel. The 24-hour hand and scale provide a reference-time display, while the independently adjustable local hour hand is the useful travel feature.
How the 216570’s GMT function works
The orange 24-hour hand points to the fixed bezel’s 24-hour scale and can show a reference time. The conventional local hour hand can be moved independently in rapid increments, allowing the wearer to adjust local time without resetting the reference-time display.
- Set the 24-hour hand to your reference time. Read it against the fixed bezel’s 24-hour graduations.
- Adjust the local hour hand when changing time zones. Its independent rapid-setting lets you change local time while retaining the reference-time indication.
- Read local time from the conventional hour and minute hands. The 24-hour display also helps distinguish day from night at the reference location.
This arrangement is useful for travel because the local hour hand can be adjusted without moving the reference-time display. The fixed scale is simple and legible, but it does not offer the rotating-bezel flexibility of a GMT-Master II.

The 216570 uses Rolex calibre 3187, a self-winding mechanical movement with independent rapid-setting of the local hour hand, instantaneous date and stop-seconds. Rolex states an approximately 48-hour power reserve and describes a paramagnetic blue Parachrom hairspring.
The reserve is usable for everyday wear, but it is shorter than the approximately 70 hours stated for the current Ref. 226570 and calibre 3285. That is a practical distinction for owners who remove a watch for a few days; it does not by itself make the older movement a poor choice.
Dial options: Polar or black?
White dial
The white dial, commonly called Polar, contrasts with the dark surrounds of its markers and hands, while the orange 24-hour hand supplies a bright accent. It has a particularly clear, instrument-like appearance.
Black dial
The black dial is more restrained from a distance. Its handset treatment can create a distinctive visual effect in certain lighting. The two dial versions share the same movement, case, bezel, bracelet and travel functions. Choose based on preference and the specific example’s condition, originality and price rather than an assumed universal value difference.

The large hands, luminous markers, contrasting dial options and fixed 24-hour scale support quick reading. Rolex’s brochure specifies a Chromalight display. The date appears at 3 o’clock beneath the Cyclops lens, adding a practical everyday function.
How does the 216570 wear?
The 42 mm case gives the 216570 a substantial presence. Case diameter alone does not determine fit, so try it on if possible and consider how the watch sits on your wrist. Wrist shape and bracelet fit matter alongside the stated diameter.
The Oyster bracelet has flat three-piece links, an Oysterlock safety clasp and a 5 mm Easylink comfort extension, according to Rolex’s reference brochure. The extension allows a small adjustment without tools.
Construction and water resistance
Rolex’s brochure specifies an Oystersteel case, screw-down Twinlock crown, sapphire crystal and 100 metres / 330 feet of water resistance. That rating is a model specification, not a guarantee that a particular pre-owned watch remains water-resistant. Ask about the individual watch’s condition and any recent testing before relying on it around water.

Pre-owned inspection checklist
Use this checklist to evaluate a specific watch. These are buyer-diligence recommendations; no physical inspection or independent authentication was performed for this article.
- Check reference and documentation. Confirm that the stated reference and dial correspond to the watch and its accompanying documents. Papers alone do not prove authenticity.
- Inspect the components and condition. Check the dial, hands, bezel, crystal and bracelet for damage, replacement parts or signs of polishing. Ask a qualified specialist for help if unsure.
- Review service records. Ask for service documentation rather than relying on a general claim that the watch was recently serviced.
- Confirm seller protections. Read the return and authenticity policy, and establish exactly what any warranty covers.
- Verify water-resistance status if needed. Ask whether the individual watch has been tested recently before wearing it in water.
Assess the watch and the seller, not just the advertised price. If considering a Rolex Certified Pre-Owned retailer, confirm the current local terms and included documents directly with the seller.

The current Ref. 226570 retains the 42 mm case, fixed 24-hour bezel and independent local-hour adjustment. Its main movement difference is calibre 3285 and an approximately 70-hour power reserve, compared with calibre 3187 and approximately 48 hours for the 216570. Rolex’s current product page identifies the 226570 as a 42 mm Oystersteel model.
| Feature | Explorer II 216570 | Explorer II 226570 |
|---|---|---|
| Movement | Calibre 3187 | Calibre 3285 |
| Power reserve | Approximately 48 hours | Approximately 70 hours |
| Case | 42 mm Oystersteel | 42 mm Oystersteel |
| Availability | Pre-owned market | Current model, subject to availability |
Compare the specific watch’s condition, completeness, seller protections and asking price as well as the movement generation. Choose the 216570 if you prefer that reference and its approximately 48-hour reserve meets your needs; consider the 226570 if its newer calibre and longer stated reserve matter more.
Who should buy the Explorer II 216570?
The 216570 may suit someone who wants a Rolex with a fixed 24-hour scale, a dedicated reference-time hand and an independently adjustable local hour hand. It is also a pre-owned purchase, so buyers should be comfortable assessing the specific watch and its seller.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Frequent travellers who value independent local-hour adjustment.
- Buyers who prefer a fixed 24-hour bezel.
- Owners who want the 216570’s design and are comfortable with its approximately 48-hour reserve.
- Buyers prepared to check condition, documentation and seller protections before purchase.
It may be a less suitable choice if you want a newer model’s approximately 70-hour reserve, or if you are not comfortable with the checks involved in buying a pre-owned watch.
Final verdict
The Rolex Explorer II Ref. 216570 combines a fixed steel 24-hour bezel, orange reference-time hand and independently adjustable local hour hand in a distinctive 42 mm design. Its approximately 48-hour reserve is shorter than the current 226570’s, and a 2026 buyer needs to evaluate the specific pre-owned watch rather than rely on a broad market claim.
Consider the 216570 for its design and travel display, and make condition, provenance, documentation and seller protections central to the buying decision.
