Its dedicated 24-hour hand works with the graduated bezel to distinguish day from night or display a second time zone. It was offered with black or white “Polar” dials, and details such as lume, bracelet, case features, and movement changed during the long production run. When assessing one, judge the individual watch’s condition, configuration, service history, and fit—not just its approximate year.
What is a Rolex Explorer II 16570?
The 16570 is a 40 mm Explorer II with a fixed bezel marked for 24 hours and a separate hand that completes one circuit of the dial every 24 hours. Rolex’s brochure for the later Explorer II generation explains that the display can help distinguish daytime from nighttime and can show a second time zone. The brochure describes the later model’s calibre 3187, not the 16570’s movements; its function explanation applies to the shared display concept, not the older watch’s specifications. Rolex Explorer II brochure.
The reference debuted in 1989 and was replaced by the 216570 in 2011. Phillips describes the 16570 as having an approximately 22-year run, while Fratello dates production to 1989–2011. Phillips’s account is an auction essay rather than a comprehensive factory production record. Phillips lot 867; Fratello buyer guide.
How do the black and Polar dials differ?
Both black and white dials are documented for the 16570. The white version is commonly called the “Polar.” The dial choice changes the visual contrast among the dial, markers, and hands; whether one is easier to read or more appealing is personal, so compare actual watches in person when possible. Fratello’s guide discusses the contrast differences and production variations. Fratello buyer guide.
#1 Best Overall

Dial and lume details also changed over the reference’s lifespan. Specialist guides distinguish tritium, LumiNova, and Super-LumiNova eras and note related dial markings. These are useful clues when comparing a watch with its claimed configuration, but an era label or dial inscription alone does not establish its date or originality. Fratello buyer guide; Beyond The Dial collector guide.
What is the difference between calibres 3185 and 3186?
Earlier 16570 examples are associated with calibre 3185 and later ones with calibre 3186. The exact transition is not consistent across the specialist sources: Fratello dates the 3186’s introduction to 2007, while Beyond The Dial places the upgrade around 2005–2006 and notes transitional examples. Treat these as approximate chronology, not a universal year or serial-number cutoff. Have the actual watch and its documentation checked by a qualified watchmaker rather than inferring its movement from a shorthand date alone. Fratello buyer guide; Beyond The Dial collector guide.

Fratello notes slight GMT-hand wobble while setting the 3185. That detail can help explain a difference between the generations, but it is not a substitute for inspecting the particular watch or confirming its calibre. Fratello buyer guide.
How did bracelets and cases change?
Bracelet and case details vary across the production run. Fratello discusses folded and solid end-link variations, drilled-lug transitions, and clasp changes; these affect appearance, fit, and the configuration a buyer should expect. Check that the bracelet suits the case and your wrist, and confirm that its end links and clasp are appropriate for the watch being offered. Do not assume that all 16570s share identical bracelet details. Fratello buyer guide.

What should you check before buying a pre-owned 16570?
Evaluate the specific watch and the evidence supplied with it. A box or papers may contribute to a complete set, but neither by itself proves the watch’s condition or originality. The available reference guides do not establish a universal authentication checklist, so a listing’s description and photographs should not replace an independent inspection when authenticity or service condition is uncertain.
- Condition: Assess the case, dial, hands, bezel, crystal, and bracelet in clear photographs or in person. Ask for details about damage, repair, or replacement parts.
- Configuration: Compare the dial, lume markings, movement, case features, and bracelet details with the claimed production era. Treat these as clues to corroborate, not proof on their own.
- Movement and service: Request available service records and documentation, and have the calibre and condition checked by a qualified watchmaker if they are material to your decision.
- Bracelet fit: Try it on if possible. Confirm the bracelet’s fit, end links, clasp, and serviceability for the specific case.
- Set contents: Record what is included—such as box and papers—and assess those items separately from the watch’s condition and originality.

How does the 16570 compare with the 216570?
The 216570, introduced as the successor in 2011, is a 42 mm generation with calibre 3187 and a larger orange 24-hour hand. The 16570 is 40 mm. The practical comparison is therefore case size, hand design, movement generation, and how each wears on your wrist—not a claim that one is objectively better. Rolex’s brochure specifications concern the later Explorer II and should not be applied to the 16570. Rolex Explorer II brochure; Beyond The Dial collector guide.
