Short answer
A 126617LB Submariner is a replica. Rolex does not publish a reference 126617LB in any catalog. The company lists the gold Submariner Date with a blue dial as 126618LB (yellow gold) and 126619LB (white gold). Replica sellers use 126617LB as a label for a gold Submariner Date copy with a blue dial and bezel.
No replica carries the weight, the movement, or the resale value of a genuine Submariner. A buyer who pays $400 for a 126617LB receives a steel case with gold plating in most cases.
What the number means
Rolex reference codes carry meaning. Collectors read the last two letters as bezel and dial color codes, written in French. LN is lunette noire, or black. LB is lunette bleue, or blue.
- 1266: Submariner Date, 41 mm case, current generation introduced in 2020.
- 18: yellow gold case and bracelet.
- 19: white gold case and bracelet.
- 13: steel and yellow gold, sold as Rolesor.
- 10: steel.
That pattern leaves no slot for a 126617LB. The listing copies a real reference instead of naming one.

Points buyers check on a replica
- Weight. A gold Submariner with the full bracelet runs about 220 g. Gold-plated replicas run 150 to 165 g.
- Bezel insert. Genuine numerals sit in the ceramic with a platinum fill. Replicas use paint or a plated film that wears at the edges.
- Dial print. Text on a genuine dial stays crisp under 10x magnification. Replica text shows rough edges and uneven spacing.
- Cyclops. Genuine crystals have anti-reflective coating under the lens. Replicas often skip it, so the date floods with glare.
- Movement. Clone 3235 movements run at 3 Hz with 40 to 45 hours of reserve. The genuine 3235 runs at 4 Hz with 70 hours.
- Engravings. Reference and serial numbers sit between the lugs. Font weight and spacing are the fastest tell.
- Clasp and hallmarks. Gold bracelets carry hallmark stamps. Plated steel does not.
- Crown action. A Triplock crown on a genuine watch turns with drag and seats in three positions. Most replicas feel loose.
Price tiers
Replica dealers sell the 126617LB in three bands.
- $120 to $250: steel case, mineral glass, 2824 or 2836 movement, plated gold finish.
- $300 to $600: 316L or 904L steel, sapphire with AR coating, better dial print, 2824 or 2836 inside.
- $700 to $1,200: clone 3235 movement, adjusted bracelet, gold plating at 3 to 5 microns, sold under the term super clone.
Genuine 126618LB watches trade in the $35,000 to $45,000 range on the secondary market. No replica holds value. Resale is close to zero.
Legal note for US buyers
Federal law prohibits trafficking in counterfeit goods under 18 U.S.C. 2320. US Customs and Border Protection seizes counterfeit watches at import. A buyer who orders a replica from overseas risks losing both the item and the payment. A local sale carries lower shipment risk and the same legal exposure for anyone who resells the watch.
What to ask before you buy
- Ask for the case weight on a scale, with a photo of the reading.
- Ask for a 10x macro shot of the dial text and the lugs.
- Ask which movement sits inside and the beat rate.
- Ask about plating thickness and any warranty on the plating.
If a seller will not send those four items, the watch is a $150 build sold at a $600 price.
