The best copy Explorer 16570 for most buyers centers on a 40mm 316L stainless steel case, drilled lugs, a Swiss ETA 2893-2 GMT movement, and a sapphire crystal with a 2.5x cyclops. I ranked candidates on five criteria: case geometry, dial and hand accuracy, GMT hand and crown function, bracelet end-link fit, and lume quality. The genuine Explorer II 16570 ran from 1989 to 2011 with a 40mm case, a fixed 24-hour bezel, and a GMT movement that tracks a second time zone. A replica worth wearing should match those dimensions and that function. No copy is a genuine Rolex, and none should be sold as one.
Case Geometry and Lug Profile
The 16570 case measures 40mm across and about 47mm lug to lug. Many replicas miss this mark by using a 42mm case that copies the later 216570.
Pros
- Correct 40mm width suits wrists from 6.5 to 7.5 inches.
- Drilled lugs let you swap straps without tools.
- A brushed finish on the lug tops matches the classic look.
Cons
- Some sellers label a 42mm case as a 16570, which is wrong.
- Heavy polishing can leave the lugs glossy and thin.
Use case: for a classic profile on a medium wrist, insist on the 40mm case and check the lug holes.
Movement Choices: Swiss ETA 2893-2 vs Asian GMT
The movement decides how the 24-hour hand and date behave. A Swiss ETA 2893-2 is the benchmark for a reliable GMT copy.

Pros
- ETA 2893-2 runs at 28,800 vph for a smooth sweep.
- Independent GMT setting lets you jump the hour hand.
- Parts and service are easy to find from watchmakers.
- A good Asian GMT clone costs less and keeps decent time.
Cons
- Swiss movements raise the total price.
- Cheap clones can show a jerky 24-hour hand or a lagging date change.
Use case: for daily wear with travel, pick the Swiss ETA 2893-2. For a weekend watch, a well-finished Asian GMT is enough.
Dial and Bezel: Polar White or Black
The Polar white dial is the signature 16570 look, with black surrounds and a red 24-hour hand. The black dial reads quieter on the wrist.
Pros
- A correct Polar dial has an eggshell white tone, not a blue tint.
- Bezel engraving should show 24 crisp numerals filled with black paint.
- Black dial versions hide small print flaws better.
Cons
- Many Polar replicas are too bright or too cold in color.
- Bezel font can be too thick or cut too deep.
Use case: choose the Polar for casual wear and summer light. Choose black for an office watch that stays under the radar.
Crystal, Bracelet, and Lume
These three parts shape the feel on the wrist more than any spec sheet suggests.
Pros
- Sapphire crystal with a 2.5x cyclops and a date that sits centered.
- Oyster-style bracelet with solid end links and a flip-lock clasp.
- Lume plots that glow even and match the hand color.
Cons
- Some crystals lack anti-reflective coating under the cyclops.
- End-link gaps and a loose clasp show up on lower grades.
- Replica lume can fade faster than the genuine coating.
Use case: if wrist feel matters most, check the bracelet end-link fit and clasp action before anything else.
Buying Checkpoints
- Confirm the case is 40mm, not 42mm.
- Ask which movement is inside and how the GMT hand sets.
- Review photos of the dial, bezel numerals, and date window.
- Check the bracelet for solid end links and a working flip-lock.
- Confirm the crystal has a cyclops at 2.5x.
A copy Explorer 16570 earns its place when the case size, GMT function, and dial color all line up with the reference. Skip anything that fails the 40mm test or hides the movement details.
