Is your Submariner
the real deal?
The Rolex Submariner is the most counterfeited watch in the world. Its iconic design makes it a prime target for fakes at every price level. Here's how to tell the difference.
How to authenticate a Submariner
Cerachrom Bezel Insert
Post-2010 Submariners use a ceramic Cerachrom bezel with engraved numerals filled with platinum PVD coating. The surface is virtually scratch-proof and will not fade. Counterfeits often use painted aluminum or low-grade ceramic with visible imperfections in the numeral fill.
Glidelock Clasp
The Oyster bracelet features a Glidelock extension system that allows 20mm of micro-adjustment without tools. It has a smooth ratcheting mechanism with precise, tactile clicks. Fakes often have a stiff, poorly machined clasp or skip the Glidelock entirely.
Lume Pip at 12 O'Clock
The luminous dot (pearl) at 12 o'clock on the bezel should be perfectly round, centered within its metal surround, and filled with Chromalight (blue glow) or Super-LumiNova (green glow on older models). On fakes, the pip is often misaligned, too large, or glows the wrong color.
Crown Guards Shape
The Submariner's crown guards (protective shoulders flanking the winding crown) have a distinct, rounded profile that blends seamlessly into the case. Counterfeits often have crown guards that are too angular, too thick, or poorly finished where they meet the case mid-section.
Rehaut Engraving Alignment
The rehaut (inner bezel ring) is engraved with repeating "ROLEX" text, and the serial number sits at 6 o'clock. On genuine Submariners, each letter aligns precisely with the minute markers. Misalignment, uneven depth, or blurry engraving is a strong indicator of a counterfeit.
Bezel Action & Weight
A genuine Submariner bezel rotates counterclockwise only with 120 distinct clicks (one per half-minute). It should feel firm with no play or wobble. The watch itself weighs around 155g (steel Oyster bracelet). Fakes are often noticeably lighter due to inferior 316L steel or hollow end links.
Submariner counterfeit warning signs
Cyclops with Weak Magnification
The Submariner Date has a cyclops lens that magnifies the date 2.5x, filling the entire window. On counterfeits, the date appears small through the lens, barely magnified at 1.5x or less. The lens may also sit off-center over the date aperture.
Dial Text Inconsistencies
Check that "SUBMARINER" and the depth rating (300m / 1000ft) use the correct font, size, and spacing. Fakes often use a slightly different typeface, inconsistent kerning, or place the text at the wrong vertical position on the dial.
Bezel Numerals Misaligned to Dial
When the bezel is set to the 12 o'clock position, the triangle marker and lume pip should perfectly align with the 12 o'clock index on the dial. The "60" numeral on the bezel should be at exact top dead center. Even slight misalignment suggests a fake or aftermarket bezel insert.
Hollow or Rattling Bracelet Links
Genuine Submariner bracelets use solid center links (since the 2000s update). If the bracelet feels tinny, rattles when shaken, or the links feel hollow or light, it is almost certainly counterfeit. Solid links have a satisfying heft and no rattling.

Frequently asked questions
Where is the serial number on a Rolex Submariner?
On modern Rolex Submariners (post-2005), the serial number is laser-engraved on the rehaut (inner bezel ring) at the 6 o'clock position. It is also engraved between the lugs on the 6 o'clock side of the case, though you need to remove the bracelet to see it. Vintage models only have the engraving between the lugs.
What is the difference between the 41mm and 40mm Submariner?
In 2020, Rolex updated the Submariner from the 40mm case (reference 116610) to a 41mm case (reference 126610). The newer 41mm version features a slightly slimmer bezel, thinner lugs, a wider bracelet, and the caliber 3235 movement with a 70-hour power reserve, up from 48 hours on the older 3135 movement.
How can I tell if my Submariner has a ceramic or aluminum bezel?
Rolex transitioned the Submariner to a Cerachrom (ceramic) bezel insert in 2010 with reference 116610. Ceramic bezels have a glossy, scratch-resistant surface with engraved numerals filled with platinum or gold PVD coating. Aluminum bezels (pre-2010) have a matte finish, are prone to fading over time, and have painted numerals that can wear off. The ceramic bezel will not fade or scratch under normal use.
