Quick Answer
126612LB does not appear in the Rolex catalog. The closest official reference is 126613LB, the two-tone blue Submariner Date 41. Sellers use the 126612LB string for replica versions of that watch, so treat any listing under this code as a replica and judge it on measurable details: case size, weight, dial print, bezel insert, movement beat rate, and clasp fit.
What the Reference Points To
The genuine watch behind the code is a 41 mm Oystersteel and 18k yellow gold Submariner Date with a blue sunburst dial, a blue Cerachrom bezel insert, an Oyster bracelet with a Glidelock clasp, and caliber 3235 with a 70-hour power reserve at 300 m water resistance. Keep that spec sheet next to any replica listing you read.
Prerequisites
- A 10x loupe, or a phone with a macro lens
- Bright, diffuse light from a window
- A jeweler's scale if you plan to compare weight
- A published spec sheet for reference 126613LB
- Awareness of your local law: in the US, selling a replica as genuine is trademark counterfeiting and fraud. Buy and wear replicas as replicas.
How to Evaluate a Replica 126612LB
- Measure the case. Genuine Submariner Date 41 cases run 41 mm wide and about 12.5 mm thick. Replicas often come in near 41 mm but sit 1 mm thicker, which changes how the watch sits on the wrist.
- Weigh the watch with all links installed. A two-tone Submariner in this size lands roughly in the 155 to 170 g range because the center links are solid gold. A plated replica comes in lighter.
- Inspect the dial under angled light. Check the sunburst finish, the coronet shape, the "1000 ft = 300 m" text, and the "SWISS MADE" split around the small coronet at 6 o'clock. Replica print often runs too heavy, and lume plots can sit uneven or in a different shade.
- Study the bezel insert. Genuine Cerachrom numerals are platinum coated and sit flush. Look for an off-center pearl, crooked markers, or a blue that shifts away from the dial tone.
- Check the cyclops and date. Genuine magnification is 2.5x with AR coating under the lens. Replica date wheels frequently show a thicker font, a crooked window, or a visible halo.
- Test the movement. Wind it, set it, and watch the date flip. Caliber 3235 beats at 28,800 vph with a 70-hour reserve. Clones and older 2824-style movements wind with more grit and hold less charge.
- Turn the crown. A genuine Triplock crown shows three dots under the coronet, crisp threads, and a clean click at each position.
- Examine the bracelet and clasp. Solid end links should sit flush at the lugs with no gap. Open the Glidelock clasp and check the stamped code on the inner blade and the sharpness of the coronet.
- Read the rehaut. The "ROLEXROLEX" engraving should align with the minute track, and the serial sits at 6 o'clock. Blurry or drifting engraving is a budget-tier sign.
- Skip the water test. Replicas ship without pressure testing. Do not swim or shower with one until a watchmaker has checked the gaskets and caseback torque.
- Compare the asking price. A genuine two-tone Submariner trades in the five-figure range. A few hundred dollars means replica, no matter what the page claims.
What "1:1" and "Super Clone" Mean
These terms describe how closely a build copies the outside of the watch. They say nothing about materials or service life. Most so-called 1:1 builds use plated gold, a generic sapphire crystal, and a movement made in a different factory than the case. Expect the plating on the center links to wear at the clasp within a year or two of daily wear.
Red Flags in Replica Listings
- Photos of a genuine watch used as product images
- No caseback, movement, or clasp photos
- Claims of solid 18k gold at a replica price
- Water resistance stated as 300 m with no test documentation
- A reference number that does not match the dial color, bezel, or bracelet in the photos
Care and Limits
Keep a replica dry, store it away from magnets, and have the movement serviced if it starts losing more than a few seconds a day. Plating, gasket quality, and bracelet tolerances are the parts that fail first. Budget for those limits before you buy, and never present the watch as genuine.
