"Replica Rolex 1666 6" is almost always a mistyped reference number. The closest real Rolex models are 16610 (Submariner Date), 16600 (Sea-Dweller), and 16613 (two-tone Submariner), all five-digit watches built between 1988 and 2010. Confirm which reference you actually want first, because the three differ in case thickness, bezel material, and movement.
What does the reference "1666 6" actually mean?
Rolex reference numbers follow a pattern, so a five-digit string can be decoded. The extra "6" in a search phrase is usually a stray keystroke or a fragment of a serial number.
- 16610: stainless steel Submariner Date, 40 mm, aluminum bezel insert.
- 16613: two-tone steel and 18k yellow gold Submariner Date.
- 16618: full 18k yellow gold Submariner Date.
- 16600: Sea-Dweller, thicker case, no cyclops, deeper dive rating.
- 16622: Yacht-Master, platinum bezel, 40 mm case.
Searching the five-digit reference gives you accurate specs. Searching "1666 6" returns noise.
Why five-digit Submariners are popular in the replica market
The 16610 uses simple geometry that factories can reproduce closely. A 40 mm case, 20 mm lugs, flat sapphire crystal, and printed aluminum bezel insert are easier to copy than a modern ceramic bezel with a platinum-filled scale. Because the original caliber 3135 has been cloned for years, mid and high tier replicas often ship with an SA3135, SH3135, or VR3135 instead of a generic ETA-style movement.
What should you check on a replica 16610?
- Case profile: crown guards should be symmetrical and softly blended into the case.
- Bezel insert: pearl position at 12 o'clock, font weight, and 10-minute marker thickness.
- Crystal and cyclops: date magnification should read near 2.5x with minimal distortion.
- Dial and hands: lume plot shape, date font, and the width of the Mercedes hour hand.
- Bracelet fit: solid end links should sit flush against the lugs with no visible gap.
- Movement: ask which caliber is installed and whether it is a decorated or functional clone.
How much do replica five-digit Submariners cost?
Budget replicas under roughly $150 usually run a low-grade automatic and often use plated brass parts. Mid tier models around $250 to $400 typically add a cloned 3135, sapphire crystal, and a 316L or 904L case. High tier builds above $450 focus on case shape, dial printing, and bracelet finishing, but no replica matches genuine tolerances or serviceability.
Are replica Rolex watches legal to buy?
Counterfeit watches infringe Rolex trademarks, and customs agencies in the United States and European Union can seize shipments. Selling a replica while calling it genuine is fraud in most jurisdictions. Check your local import rules before ordering anything.
Frequently asked questions
Is a replica 16610 waterproof?
Factories often claim water resistance, but gaskets and case finishing vary widely. Treat any replica as splash resistant at best and have it pressure tested before swimming.
Can a replica 16610 take genuine Rolex parts?
Genuine components rarely fit without machining. Thread pitches, stem lengths, and dial feet usually differ from the original specification.
Which clone movement is closest to the Rolex 3135?
The VR3135 and SH3135 clones copy the layout and winding feel more closely than generic 2836-based movements, though none match genuine accuracy or service intervals.
Did Rolex ever make a reference 1666?
No standard Rolex reference is simply 1666. If you see that number attached to a Submariner listing, treat it as a typo or a seller error.
