The fastest way to spot a fake Rolex 116613 is to read the bezel and the gold together. On a genuine Cerachrom insert the numerals sit recessed and filled flush with matte 18 ct gold, while fakes show raised, painted or misaligned markings. Real gold on this reference is solid 18 ct with a warm, even tone across the center links, not plating with a brassy or orange cast.
What is the quickest five-second check?
Weigh it in the hand and look at the color transition where steel meets gold. A complete genuine 116613 on its Oyster bracelet sits around 150 to 160 grams, and the gold center links feel dense rather than hollow. Plated fakes feel light, and the gold tone drifts toward yellow-orange in daylight.
Then tilt the watch under a lamp and watch the bezel numerals catch the light. Genuine gold fill sits inside the ceramic, so the surface stays level. Fake inserts often show a raised ridge you can feel with a fingernail.
How do the bezel and insert give a fake away?
- Insert color: genuine blue is deep and even. Fakes skew bright, purple or patchy.
- Pip: the lume pearl sits in a gold ring at 12, centered and flush. Crooked or domed pearls are a red flag.
- Numerals: crisp serif edges with no bleed and no paint sitting on top of the ceramic.
- Action: 120 clicks, firm and consistent, with no springy back-play.
What should the dial, hands and rehaut look like?
The sunburst blue dial shifts from bright to near navy as you rotate it, and the print stays razor sharp. Fake dials show flat paint, thicker lettering, or a coronet with uneven points and a closed gap under the crown.
Look at the rehaut ring between the dial and the crystal. ROLEXROLEXROLEX should repeat with each R aligned to a minute marker and the engraving depth constant. Wobbly spacing or shallow laser etching points to a replica.
Hands and hour markers carry gold surrounds with clean edges and blue Chromalight lume. Check the glow: it should read soft blue, not green.
How do you check the date and cyclops?
The cyclops magnifies about 2.5 times, so the date fills the window without crowding it. Genuine crystals carry anti-reflective coating under the cyclops, which shows a faint blue tint at an angle and keeps the date readable.
Date font matters too. The numerals are upright and spaced with a flat top on the 1. On fakes the date looks oversized, sits off center, or glows milky around the edges.
What about the case and crown?
The case is 40 mm with sharp, unpolished lug bevels and a smooth flow into the lugs. The Triplock crown shows three dots under the coronet, crisp threads, and a rubber gasket that seals without grit. Fake crowns feel loose and often sit proud of the case.
How do you inspect the bracelet and clasp?
Solid end links should fit the lugs with no gaps and no wobble, and the SELs on each side mirror each other. Fakes often leave a visible step or a gap you can see through.
Open the Glidelock clasp. Inside you should find sharp stamping, a 750 hallmark on the gold components, and STEELINOX on the steel. Engraving on a fake is shallow, uneven, or missing the hallmark entirely.
What do the caseback and movement reveal?
The 116613 has a solid caseback with no display window, so anyone showing an exhibition back is showing a fake. Between the lugs at 12 o'clock you should find the reference 116613, and at 6 o'clock the serial, both struck deep and clean.
Calibre 3135 runs at 28,800 vibrations per hour, which is eight beats per second and a smooth sweep. Listen for a clean tick and check the reserve, about 48 hours. A stuttering seconds hand or a 21,600 vph beat is a strong tell.
Red flags checklist
- Price far below market for a two-tone Submariner.
- Gold plating worn thin at the clasp edges or between links.
- Painted or raised bezel numerals.
- Misaligned rehaut engraving.
- Green lume instead of blue.
- No 750 hallmark anywhere on the bracelet.
- Seller refuses a movement or caseback inspection.
When should you walk away?
Walk away when the seller cannot show the reference and serial between the lugs, or when the watch arrives with stickers covering the caseback. Box, papers and service history support authenticity, but they are easy to fake, so trust the physical checks first.
If two or more checks fail, treat the watch as a replica regardless of the story attached to it.
