A fake Rolex Submariner 16610LV almost always fails on four points: the green bezel insert, the maxi dial, the case engravings, and the movement. Run the checks below in order. The full inspection takes about ten minutes with a loupe and a bright, angled lamp, and it works whether the watch is in your hand or in photos.

Before You Start

  • 10x jeweler's loupe
  • Bright lamp you can angle across the case
  • Calipers or a digital micrometer
  • Reference photos of a known-genuine 16610LV from the front, back, and lug area
  • A serial-era chart covering the 16610LV production run
  • Spring bar tool, if you plan to read the engravings between the lugs

1. Read the Bezel Insert

  1. Hold the watch at an angle under the lamp and judge the green. The genuine anodized aluminum insert is a flat, slightly muted green. Copies lean emerald, neon, or candy-bright.
  2. Inspect the lume pip at 12. On a genuine insert it is a small dome seated level in the insert, centered over the triangle. Fakes run flat, oversized, or off-center.
  3. Compare numeral thickness and spacing on the 10, 20, 30, 40, and 50. Genuine markers are cut to an even weight. Copies show thin strokes, crowded spacing, or index lines of unequal length.
  4. Rotate the bezel. A genuine 16610LV turns through 120 crisp clicks with no wobble and no side play. A loose or gritty action is a fail.
  5. Look at the insert edge where it meets the steel ring. Genuine sits flush with a thin, even gap. Raised or pinched edges point to a replacement insert.

2. Check the Maxi Dial and Hands

  1. Measure the hour markers. The 16610LV carries the larger maxi plots in white gold surrounds. Copies often keep standard-size markers or print the lume instead of applying it.
  2. Check the lume tone across all plots. Every marker should match in color and texture, with no patchy or grainy fill.
  3. Darken the room and compare the glow. Plots should light up evenly and fade at the same rate. Mixed glow colors across the dial mean a relume or a fake.
  4. Examine the Mercedes hour hand, minute hand, and seconds hand. Maxi hands are wider than a standard Submariner hand set, with clean edges and a properly domed lume plot on the seconds hand.
  5. Read the printed signature lines: ROLEX, OYSTER PERPETUAL DATE, SUBMARINER, and the depth rating. Genuine print is crisp and centered under 12. Fuzzy, thick, or double-struck text ends the inspection.
  6. Look at the date window. Magnification should sit near 2.5x, with the date centered and the correct numeral shape.

3. Inspect the Case, Lugs, and Engravings

  1. Remove the bracelet with a spring bar tool and read the serial between the lugs at 12.
  2. Read the reference number between the lugs at 6. It must read 16610, not 16610LN or a smooth blank.
  3. Compare the engraving to a serial-era chart. Early 16610LV examples carry drilled lug holes, and later production does not. A drilled case paired with a late serial is a red flag.
  4. Study the engraving depth and font under the loupe. Genuine markings are laser-cut to an even depth with clean character shapes. Shallow, uneven, or hand-scratched numbers are a fail.
  5. Measure the case at 40mm across, excluding the crown. Copies often run a fraction large or small.
  6. Check the caseback. It is solid steel with no display window. Any exhibition back means the watch is not genuine.

4. Examine the Crown, Crystal, and Rehaut

  1. Inspect the winding crown under the loupe. It is a Triplock with three dots below the coronet, and the threads should engage smoothly for several turns.
  2. Look at the crystal at 6 o'clock for the laser-etched coronet. Genuine etching is tiny, centered, and visible only at 10x.
  3. Angle the light across the cyclops. Genuine sapphire carries no anti-reflective coating, so there should be no blue or purple halo.
  4. Check the rehaut ring. Later serials carry the ROLEX ROLEX ROLEX engraving and early ones do not. A mismatch with the serial range is a fail.

5. Check the Bracelet and Clasp

  1. Confirm the bracelet is a 93250 Oyster with solid end links.
  2. Look for the reference stamp on the last link near the clasp and the end link code on the inner face.
  3. Check the clasp stamping. Genuine marks are deep, aligned, and include STEELINOX. Shallow, crooked, or misspelled stamps end the inspection.
  4. Test the flip-lock and the divers extension. The lock snaps shut with a firm click and the extension folds without slack.
  5. Verify each link uses a slotted screw pin. Pressed pins are a common shortcut on copies.

6. Verify the Movement

  1. Take the watch to a watchmaker and have the caseback opened with a proper tool.
  2. Identify the caliber. The 16610LV runs a Rolex 3135, stamped 3135 on the bridges.
  3. Look for the Rolex coronet and engraving on the rotor and bridges, plus even Geneva stripes and clean perlage.
  4. Listen to the beat. The balance runs at 28,800 vibrations per hour, so the seconds hand sweeps smoothly with no stutter.
  5. Test the crown functions: winding, quickset date, and hacking seconds when the crown is pulled out.

7. Paperwork and Price

  1. Match the serial on the warranty card or paper to the serial between the lugs.
  2. Check the box and paperwork fonts against a known set for the production year.
  3. Compare the asking price against current market listings. A genuine 16610LV sells at a strong premium, so a bargain price is the loudest warning sign of all.
  4. Stop the deal if two or more checks above fail. Buying or selling a counterfeit watch is illegal in the United States, and there is no recourse once cash changes hands.

Two failures are enough. A genuine 16610LV is consistent across every detail, and copies are not.
