The current 42mm Explorer II sits close to retail in the secondary market, making it one of the more accessible entry points into modern Rolex sport watches.
Editorial estimate. Actual prices vary by condition, date, and box/papers status. Live pricing data is in development.
The Explorer II 226570 is a 42mm steel tool watch built around a fixed 24-hour bezel and a GMT hand, designed for environments where AM/PM ambiguity is a genuine problem. Available in white or black dial, it is the current-production successor to the 216570 and runs the same-generation movement as the modern Datejust and Submariner families.
The 226570 launched in 2021, replacing the 216570 which had run from 2011 with the caliber 3187. The new reference brought the caliber 3285, adding the Chronergy escapement, improved power reserve (70 hours), and better magnetic resistance. Dial options are white (polar) or black, continuing the split that has defined the Explorer II since the 1980s.
The 42mm case size, introduced on the 216570, carries over unchanged from its predecessor.
Check the bracelet end links for play and the clasp for wear, as pre-owned examples accumulate wrist wear quickly and a stretched bracelet is the most common deduction. Confirm the dial is original to the case: white dials should show clean printing with no yellowing or shadow text. The fixed 24-hour bezel should rotate freely for chapter-ring verification but is non-functional as a timer, so bezel condition matters only cosmetically.
Prefer examples with original crown tube intact, as 42mm cases with deep scratches at the crown-side lug are hard to restore without professional polishing that rounds the edges.
The 226570 trades near retail or at a modest premium given current authorized-dealer availability improving in many markets. White dial examples have historically commanded a slight premium over black in the secondary market, though the gap is narrow on this reference. Full-set examples with unworn bracelet links and original sticker remnants outperform watch-only sales.
Being a current-production reference, prices are sensitive to retail availability fluctuations.
The caliber 3285 is the current-generation Rolex movement and is built for long service intervals, with Rolex recommending approximately 10 years between services. It is too new for most pre-owned examples to require service, so a seller claiming a recent full service on a 2021-2023 example warrants scrutiny. When service is eventually needed, expect costs in the $800-1,200 range at an independent watchmaker or significantly more through Rolex service centers.
Community + OSINT signals haven’t landed for this reference yet. We don’t publish a rating against zero signal — the number would mean nothing. Editorial body + caliber + market value still surface above; ratings appear once the signal corpus does.
The 226570 is a recent reference with traceable production history; the fixed 24-hour bezel and orange GMT hand at the 24-hour position are the primary authentication points.
