The Rolex Submariner 16618 is the all-gold Submariner Date: a 40 mm Oyster case in solid 18k yellow gold, a matching gold bezel, and a blue or black dial. A "replica 16618" is a counterfeit copy, not a Rolex product, and no replica reproduces the reference's solid gold case, bracelet, or caliber 3135 movement. Buyers searching this term are usually weighing two questions at once: what makes the 16618 distinctive, and how far a replica can actually get.
What are the specs of the Rolex Submariner 16618?
The 16618 measures 40 mm across, uses a screw-down crown and caseback, and carries a sapphire crystal with a cyclops magnifier over the date. It is rated to 300 meters, matching the stainless Submariner Date of its era. Inside sits the Rolex caliber 3135, a bidirectional automatic movement with a 48-hour power reserve.
What is the difference between 16618LB and 16618LN?
Those suffixes describe dial and bezel color. LB marks the blue sunburst dial with a blue bezel insert, while LN marks the black dial with a black insert. Blue examples tend to draw higher collector interest, and dial condition drives value more than any other single factor.
Is a 1:1 replica the same as a real 16618?
No. Replicas almost always build on stainless steel or base metal with gold plating or physical vapor deposition. A genuine 16618 has a case, bezel, and Oyster bracelet cast in solid 18k gold, so the weight, the metal hardness, and the stamped hallmarks all differ from a plated copy. Plating also wears through at the clasp and lugs, which is where fakes usually show themselves first.
How do you tell a replica from a genuine 16618?
- Weight and balance: solid gold feels distinctly heavier than gold-plated steel on the wrist and in the hand.
- Hallmarks: look for 750 or 18k stamps, the Rolex crown, and crisp hallmark punches on the case, lugs, and clasp.
- Engravings: the reference number between the lugs and the caseback markings should be clean, deep, and correctly spaced.
- Dial printing: text, coronet, and lume plots should be sharp, with no bleeding or off-center markers.
- Movement: a genuine 3135 shows proper finishing and correct beat rate, which low-grade replica movements do not match.
Are replica Rolex watches legal to buy in the United States?
No. Trafficking in goods that infringe a registered trademark is a federal offense under 18 U.S.C. Section 2320, and U.S. Customs and Border Protection can seize counterfeit shipments at import. Sellers also face civil liability from the trademark owner. A counterfeit carries no Rolex warranty and cannot be serviced by an authorized watchmaker.
What should a buyer do instead?
Shop the genuine reference through an authorized dealer or a specialist vintage dealer, and insist on box, papers, and a service history. Have any pre-owned 16618 authenticated by an independent watchmaker before money changes hands. Pricing varies widely with dial color, condition, and completeness, so check current market listings rather than trusting a single quoted figure.
