Short answer
The Rolex 116619 is the 40mm white gold Submariner Date with the blue dial and blue bezel, the model collectors call the Smurf. A fake 116619 is a replica built to copy that look, and in almost every case the case is 316L or 904L steel with a plating or a PVD tint, not 18k white gold. The reference number on a replica is a label the seller chose. It is not a material spec, and it is not a guarantee of anything inside the watch.
What the genuine reference is
- Reference 116619LB, Submariner Date, 40mm case.
- Solid 18k white gold case and bracelet, produced from 2008 to 2020.
- Blue sunray dial, blue Cerachrom ceramic bezel insert with platinum-filled numerals.
- Caliber 3135, 28,800 vph, roughly 48 hours of power reserve.
- Replaced in 2020 by the 126619LB, which moved to a 41mm case and caliber 3235.
What replica versions actually are
Replicas of this reference fall into rough tiers, and the tier decides what you are holding.
- Entry tier: steel case, painted or printed bezel insert, low-beat Chinese movement, folded or thin bracelet. The blue is usually too bright or too purple.
- Mid tier: steel case with a ceramic insert, clone of an ETA 2824 or a low-grade 3135 copy, better dial printing. Bezel numerals are painted rather than recessed and filled.
- Top tier, often marketed as 1:1: closer case geometry, clone 3135, ceramic insert with recessed numerals, applied indices with decent lume. Still steel, still not gold, still not serviceable by Rolex.
The white gold problem
No replica of the 116619 is made of 18k white gold, because the raw gold in the case and bracelet would cost more than the finished replica sells for. White gold is also dense, so a genuine 116619 weighs several tens of grams more than a steel Submariner. If a seller claims solid white gold at a replica price, the claim is false. The most common substitute is steel with rhodium plating, which looks close in a photo and wears through at the clasp and lugs within months.
Checks to run before you spend money
- Request daylight photos of the case flanks, caseback, clasp and rehaut, not studio shots.
- Weigh the watch on a kitchen scale. Steel Submariner weight is around 155 grams; white gold runs well above that.
- Look at the bezel insert numerals. Genuine ones are recessed and platinum-filled. Painted or raised numerals mean a lower tier.
- Ask for a timegrapher photo. The caliber 3135 beats at 28,800 vph; many cheap replicas run at 21,600.
- Check the rehaut engraving alignment against the minute markers. Misalignment is a common tell.
- Inspect the end link fit at the lugs and the crown action in person if you can.
- Treat any claim of solid gold, box and papers, or Rolex service history as a red flag unless the price matches a genuine watch.
Legal and practical reality in the US
Trafficking in counterfeit goods is a federal offense under 18 U.S.C. 2320, and shipments of counterfeit trademarked items are subject to seizure and destruction at the border. Buying for personal use does not make a replica legal to import, and reselling one as genuine exposes you to criminal and civil liability. There is also no recourse: Rolex will not service a replica, the warranty does not exist, and parts for clone movements are not standardized, so a repair often costs more than the watch. If the goal is the blue Submariner look on a budget, a legitimate steel dive watch is the lower-risk route. If the goal is a 116619, only a genuine one is white gold.
