The Rolex 116619LB is the 18k white gold Submariner Date with a blue dial and blue Cerachrom bezel, known among collectors as the Smurf. A fake Rolex 116619 imitation watch lives or dies on weight and metal density, because the genuine piece is a solid gold dive watch that feels noticeably heavier than any steel Submariner. Buyers who study this reference learn to judge an imitation by heft, bezel finish, dial color, and movement type rather than by photographs alone.
What makes the 116619LB different from a steel Submariner?
Rolex built the 116619LB from 2008 until 2020, then replaced it with the 126619LB. The case measures 40 mm, carries a blue Cerachrom ceramic bezel insert, and is rated to 300 meters of water resistance. Under the caseback sits a caliber 3135 automatic movement with roughly 48 hours of power reserve.
Every external part that touches the wrist on the genuine watch is 18k white gold, including the case, crown, bezel, and full bracelet. That single fact drives the price gap between this reference and a standard stainless steel Submariner Date.
What should you inspect on a 116619 imitation watch?
Weight and metal density
A genuine 116619LB on its full bracelet typically lands near 240 to 260 grams, depending on how many links are fitted. Replicas using standard steel cases usually fall 80 to 120 grams lighter than that range. High-tier versions close the gap with tungsten alloy or gold-plated brass mid-links, and the difference is obvious the moment you pick one up.
The Ultimate Guide to Buying Imitation Rolex 116619 Watches
Bezel insert and Cerachrom finish
The genuine blue Cerachrom insert has a deep, slightly matte ceramic surface with platinum-coated numerals that sit nearly flush. Inexpensive copies show a glossy plastic-like insert, raised or uneven markings, and a blue that shifts toward purple under indoor light. Run a fingernail across the numerals to feel for depth and paint thickness.
Dial, hands, and date window
The 116619LB dial is a saturated blue sunburst with white gold hour markers and a Cyclops lens over the date. Common flaws in imitations include a flat or overly bright blue, misaligned marker surrounds, and a Cyclops that magnifies poorly or sits off-center. Check the date font and the alignment of the crown at 12 o'clock against the lugs below.
Movement, caseback, and engravings
Genuine pieces run the caliber 3135, while most imitations use Asian automatic movements such as the 2824 or 2836 clones. Look at the sweep of the seconds hand, the click of the winding crown, and the engraving depth between the lugs. Laser-etched coronet details at 6 o'clock are often too large or too faint on copies.
Bracelet and Glidelock clasp
The Oyster bracelet on this reference uses solid gold links and a Glidelock extension system with fine adjustment. Imitations frequently show hollow end links, loose SEL fit against the case, and a clasp that feels thin or gritty when opened. Tight tolerances between the end link and case are one of the clearest tells.
How do replica tiers differ for this reference?
- Entry tier: steel case, plated finish, mineral glass, and a low-grade automatic movement. Weight and bezel color are far off.
- Mid tier: better dial printing, ceramic bezel insert, and a reliable clone movement, but still too light in the hand.
- Top tier: tungsten or gold-capped case, sapphire crystal with proper Cyclops, accurate blue dial, and a decorated clone movement built on the 3135 platform.
Price generally tracks the metal work, not the movement, for this specific reference. A heavier case and a correct blue Cerachrom insert matter more than an elaborate rotor engraving.
Frequently asked questions
How heavy should a 116619 imitation be?
Aim for roughly 230 to 260 grams on a full bracelet. Anything under 180 grams is almost certainly a steel case with plating rather than a dense alloy.
Which movement appears in high-tier versions?
Most quality imitations use a decorated clone of the caliber 3135 or a modified ETA-style automatic. Both offer a smooth sweep and reliable timekeeping when serviced.
Is the blue dial color hard to replicate?
Yes. The sunburst blue changes with lighting angle, and most copies read flat or too dark in person. Compare a candidate dial outdoors in daylight before deciding.
Why do collectors call it the Smurf?
The blue dial and blue bezel on a white gold case earned the nickname shortly after launch in 2008. The name stuck through the 2020 discontinuation.
