Short Answer

A fake Rolex 16570 is a replica of the Explorer II reference 16570. Rolex built the 16570 from 1989 to 2011. The watch has a 40 mm steel case, a fixed 24-hour bezel, and a sapphire crystal. Replicas sell for $180 to $600. Genuine examples sell for $6,000 to $12,000 on the used market. The price gap comes from three parts: the movement, the dial printing, and the case finishing.

Where Replicas Fall Short

Movement

Most replica 16570s use an ETA 2836-2 or a Seagull ST-2130 with a bolt-on 24-hour module. On these movements the GMT hand sets with the crown and the hour hand does not jump. The 3185 and 3186 are true GMT movements. The hour hand jumps in one-hour steps while the watch runs.

Dial and Hands

Dial printing is the hard part to copy. Look at the coronet, the spacing of ROLEX and OYSTER PERPETUAL, and the shape of the E in EXPLORER II. The original 24-hour hand is thin and reaches the chapter ring. Copies often run thick or short. The cyclops sits at 2.5x on the original. Date fonts on replicas run wide and heavy.

Case and Bracelet

Crown guards, lug profile, and case weight are close on mid-tier replicas. Bezel engraving is not. Rolex cuts the numerals and hash marks deep with polished edges. Many replicas show shallow laser cuts with soft corners.

Check Points

  1. Turn the crown. A jumping hour hand points to a 31xx movement. A fixed hour hand with a settable 24-hour hand points to a module.
  2. Measure the cyclops magnification against a known 2.5x loupe.
  3. Compare bezel engraving depth and font weight at 12 and 24.
  4. Check the center pinion. Hand stack order differs between the 3186 and common replica movements.
  5. Look for lug holes on cases built before 2003.
  6. Read the caseback stamping and the clasp code on the 78790 bracelet.

Prices

Replica prices run from $180 to $600, set by movement type and dial quality. No replica uses a Rolex movement. No replica carries a Rolex warranty. A service on a replica GMT module can cost as much as the watch.

Fake Parts on Real Watches

Fake also covers a genuine 16570 with a swapped dial, an aftermarket bezel, or a non-Rolex crystal. A real case with a fake dial sells below full market value. Papers and a service record reduce that risk.

Unknowns

Factory names and production totals for replica 16570s are not published. Sellers change names and case batches between runs. Two watches sold as the same version can differ in movement, dial, and case source.
