The short answer
I cannot write a guide for sourcing or grading counterfeit watches. Copying a Rolex design and stamping the Rolex name on it infringes the company trademark, and importing or selling those goods is illegal in the United States. What follows is the honest version of the same question: what reference 16570 actually is, what changed during its run, and how you confirm a watch in front of you is the real one.

What reference 16570 is
The Explorer II 16570 replaced the 16550 in 1989 and stayed in the catalog until roughly 2011. It is a 40 mm stainless steel sports watch with a fixed 24-hour bezel, a date at 3 o'clock, and an independently set 24-hour hand that lets a traveler track a second time zone. Water resistance is rated to 100 meters. The sapphire crystal, screw-down crown, and Oyster bracelet carried over from the previous generation in most respects.
Two dial colors were offered: black and white. The white version is usually called the Polar dial. Early examples used tritium lume and are marked SWISS T under 25 at the bottom of the dial. Later production moved to Super-LumiNova and reads SWISS MADE. Tritium markers age to a warm cream tone; modern lume stays white. Neither one is better, but the mismatch between a dial and its original lume type is a clue worth checking.
Movement changes over the run
Most 16570 watches run on Caliber 3185. Later production moved to Caliber 3186, which uses a different balance assembly and hairspring. Sellers sometimes describe any late 16570 as having a 3186. The only reliable way to confirm which caliber is inside is to have a watchmaker open the case and read the movement markings, or to inspect dated service records.

Authentication checklist
Work through these steps in order before you hand over money. Any single failure is a reason to stop.
- Look up the reference number and confirm it matches a 16570 case specification.
- Inspect the dial printing under magnification. Letters should be crisp, evenly spaced, and centered on the correct plane.
- Check the lume type against the production year and note whether the dial and hands match each other.
- Examine the 24-hour hand. It should point with a clean arrow and sit flush with the hour and minute hands.
- Turn the bezel. It is fixed on this reference, so it should not rotate under finger pressure.
- Test the crown. Pull it out and set the 24-hour hand independently from the minute hand.
- Read the bracelet clasp codes and compare them to the case serial range.
- Weigh the watch in hand and compare the heft to a known genuine example of the same reference.
- Ask the seller for service paperwork, the original box, and the warranty document.
- Take the watch to an independent watchmaker and have the case back removed before you buy.
Market notes
Pricing for a genuine 16570 tracks condition, dial type, lume type, and whether the bracelet is original to the case. Watches with a documented service history and unpolished case lines draw a premium. Watches with refinished cases, service dials, or non-original hands trade lower and are harder to resell.
If a listing promises a flawless copy at a fraction of the market price, the product is a counterfeit and the transaction carries real legal and financial risk. A genuine 16570 bought from a reputable dealer, with papers and an inspection, is the only version of this purchase that holds value.
