How to Authenticate a Rolex: The 12-Point Verification Guide
Counterfeit Rolex watches have become increasingly sophisticated. Modern "super clones" can fool casual observers and even some jewelers. This guide covers the 12 authentication checkpoints used by professional watch dealers and collectors to verify a Rolex is genuine.
Important disclaimer: No single test is definitive. Professional authentication should always be performed before purchasing a high-value watch. On eBay, watches over $2,000 qualify for the free Authenticity Guarantee program, which includes professional verification before delivery.
Quick Authentication Checklist
1The Sweep Test
A genuine Rolex uses a mechanical automatic movement that beats at 28,800 vibrations per hour (8 beats per second). This creates the signature smooth sweeping second hand.
Genuine Rolex
Second hand sweeps in a fluid, continuous motion. At 8 beats per second, individual ticks are virtually invisible to the naked eye.
Common Fake Tells
Second hand visibly ticks once per second (quartz movement) or sweeps with a noticeably jerky motion. Note: high-end "super clones" now use automatic movements that also sweep, so this test alone is not definitive.
2Cyclops Magnification
The cyclops lens (date magnifier) on genuine Rolex Date models provides exactly 2.5x magnification. This is one of the most reliable quick checks.
Genuine Rolex
Date fills most of the cyclops window and appears very large and sharp. The lens has anti-reflective coating on the inner surface, making it nearly invisible from an angle.
Common Fake Tells
Date appears small within the cyclops (only 1.5x magnification). The lens may have a visible blue or green tint from incorrect coating. Some fakes omit anti-reflective coating entirely.
3Crown Logo at 6 O'Clock
Starting around 2002, Rolex laser-etches a tiny crown logo on the crystal at the 6 o'clock position. It's a micro-etching that's extremely difficult to see without a loupe.
Genuine Rolex
A tiny, finely detailed Rolex crown is barely visible to the naked eye — you need to tilt the watch to catch it. Under magnification (10x+), it appears as a circle of tiny dots.
Common Fake Tells
Either missing entirely, or too visible to the naked eye (overdone etching). Under magnification, it appears as solid lines rather than dots, or has rough, uneven edges.
4Serial and Model Number Engravings
The serial number (6 o'clock side) and model/reference number (12 o'clock side) are engraved between the lugs. On genuine Rolex, these are deeply and precisely cut.
Genuine Rolex
Characters are deeply engraved with clean, sharp edges. Each character is perfectly aligned and evenly spaced. The engraving catches light and casts tiny shadows.
Common Fake Tells
Characters are etched (shallow), printed, or sand-blasted rather than deeply engraved. Spacing may be uneven, characters may be different sizes, or the font style is wrong.
5Rehaut Engraving (Post-2007)
Since approximately 2007, Rolex engraves "ROLEX ROLEX ROLEX" repeatedly around the rehaut (the inner ring between the dial and crystal). The serial number also appears at 6 o'clock.
Genuine Rolex
Engraving is crisp, evenly spaced, and precisely aligned with the dial markers. The serial number at 6 o'clock matches the one between the lugs.
Common Fake Tells
Engraving is misaligned with dial markers, unevenly spaced, or has inconsistent letter depth. Serial number at rehaut doesn't match between-the-lugs serial, or is missing entirely.
6Weight Test
Genuine Rolex watches use 904L stainless steel (denser than standard 316L) and high-quality movements. This makes them noticeably heavy for their size.
Genuine Rolex
A genuine steel Submariner (126610LN) weighs approximately 155 grams. A Datejust 41 is about 135-140g. The watch feels substantial and well-balanced.
Common Fake Tells
Significantly lighter due to cheaper steel alloys, hollow links, and lighter movements. Some high-end fakes use 316L steel which is close but still slightly lighter.
7Case Back
Modern Rolex watches (post-1950s for most models) have completely smooth, plain stainless steel casebacks with no engravings, no crystal display, and no stickers.
Genuine Rolex
Smooth, plain caseback with no logos, text, or engravings. The only modern exceptions are some Cellini models and the Sea-Dweller. The caseback has fine concentric machining marks.
Common Fake Tells
Has Rolex logo, crown, text engravings ("ORIGINAL ROLEX DESIGN"), or a see-through crystal display back on models that shouldn't have one (Submariner, Datejust, GMT-Master, etc.).
8Dial Quality
The Rolex dial is one of the most difficult components to replicate. Genuine dials have a level of finish and precision that is immediately apparent under magnification.
Genuine Rolex
Hour markers are perfectly aligned and evenly applied. Text printing is crisp with no bleeding or fuzzy edges. Lume plots are identical in size and shape. The Rolex crown logo above "ROLEX" at 12 o'clock is perfectly proportioned.
Common Fake Tells
Slight misalignment of markers, uneven text spacing, bleeding ink on printed text, inconsistent lume plot sizes, or the crown logo proportions are wrong. The dial color or texture may also be slightly off.
9Bezel Quality
Modern Rolex sport watches (Submariner, GMT-Master II, etc.) use a Cerachrom ceramic bezel insert that is virtually scratch-proof and has an unmistakable quality feel.
Genuine Rolex
Cerachrom ceramic bezel has numbers and markers that are filled with PVD platinum or gold coating. The bezel clicks crisply in either direction (or one direction for dive bezels) with exactly 120 clicks per rotation. Colors are deep and consistent.
Common Fake Tells
Bezel insert may be aluminum or painted ceramic. Numbers/markers may be painted on rather than filled. Click action is mushy, has fewer clicks per rotation, or clicks in both directions when it shouldn't. Color may fade or chip.
10Crown and Winding
The Rolex crown (winding crown) has the Rolex logo engraved on the end and features a Triplock or Twinlock seal system for water resistance.
Genuine Rolex
Crown logo is deeply and precisely engraved. Unscrewing the crown requires exactly 7-8 turns. The crown pulls out to two positions (date and time) with definite clicks. Winding is buttery smooth with no grinding.
Common Fake Tells
Crown logo is shallow, misshapen, or painted. Crown unscrews too easily or requires too many turns. Winding position transitions are vague. Winding feels gritty or has a grinding sensation.
11Bracelet and Clasp
Rolex bracelets use 904L steel links with solid endlinks and a precision-engineered clasp with micro-adjustment holes (Glidelock or Easylink).
Genuine Rolex
Bracelet links are solid (no hollow center links on modern models). Clasp has Rolex crown logo, smooth operation, and micro-adjustment system. Links articulate smoothly with no side play.
Common Fake Tells
Center links may be hollow (lighter weight). Clasp logo is poorly detailed. Micro-adjustment holes are absent or poorly machined. Links have excessive side play or rattle.
12Warranty Card and Documentation
Modern Rolex watches come with a green warranty card (or beige for older models) containing the serial number, model reference, and dealer information.
Genuine Rolex
Green plastic card (post-2020) or green/beige paper card (older). Serial number matches the watch. Has dealer stamp, date of purchase, and model reference. COSC chronometer certification tag may be included.
Common Fake Tells
Card feels wrong (too thick, too thin, wrong material). Serial number doesn't match the watch. Dealer information is missing or generic. Spelling errors or wrong fonts. Some fakes don't include any documentation.
Where to Get a Rolex Professionally Authenticated
- Authorized Rolex Dealer (AD)
The most reliable option. ADs can verify serial numbers against Rolex's database and inspect the movement. Many offer free visual checks if you're a customer. Full service inspection with authentication runs $200-$500.
- Certified Independent Watchmaker (CIW)
Watchmakers certified by the American Watchmakers-Clockmakers Institute (AWCI) or equivalent organizations can open the caseback and verify the movement. Typically $100-$300. Ask for their Rolex experience specifically.
- eBay Authenticity Guarantee
Watches over $2,000 on eBay are automatically enrolled in the Authenticity Guarantee program. A third-party authentication expert inspects the watch before it's shipped to the buyer — at no cost. This is the safest way to buy on eBay.
- Online Authentication Services
Services like BeckerTime, Bob's Watches, and Craft & Tailored offer authentication via submitted photos ($25-$75). Less reliable than hands-on inspection but useful for initial screening before committing to a purchase.
Red Flags When Buying a Rolex on eBay
- Price more than 25% below current market value — if it seems too good to be true, it is
- Stock or catalog photos instead of actual photos of the watch being sold
- Seller won't provide additional photos of serial number, caseback, or between-the-lugs engravings
- Seller has fewer than 100 transactions or below 98% positive feedback
- Listing doesn't mention eBay Authenticity Guarantee for watches priced above $2,000
- Warranty card serial number doesn't match the watch serial (or card is not shown)
- International shipping from known counterfeit hotspots with no return policy
- "Like Rolex" or "Rolex style" language — legitimate sellers don't need these phrases
- Missing box, papers, and warranty card with no explanation of provenance
Check the Serial Number
Use our free serial number lookup tool to verify the production year of any Rolex. If the serial doesn't match the seller's claimed year, it's a major red flag.

Frequently Asked Questions
How can you tell if a Rolex is real?
To tell if a Rolex is real, check these key indicators: (1) the second hand should sweep smoothly, not tick; (2) the cyclops lens over the date magnifies 2.5x; (3) the laser-etched Rolex crown at 6 o'clock on the crystal is barely visible to the naked eye; (4) the serial and model numbers between the lugs are deeply engraved, not etched or printed; (5) the weight should feel substantial — a genuine steel Submariner weighs about 155g; (6) the rehaut (inner bezel ring) on post-2007 models has 'ROLEX' engraved repeatedly. For the most reliable authentication, have the watch inspected by an authorized Rolex dealer or a certified independent watchmaker.
How to spot a fake Rolex on eBay?
On eBay, watch for these red flags: prices more than 25% below market value, stock or catalog photos instead of photos of the actual watch, sellers with fewer than 100 transactions or below 98% positive feedback, missing or generic warranty cards, and listings that don't show the serial number or between-the-lugs photos. Always buy watches over $2,000 that qualify for eBay's Authenticity Guarantee program, which verifies the watch before delivery. Request additional photos if needed — legitimate sellers will comply.
What is the Rolex cyclops test?
The cyclops test checks the magnification lens over the date window on Rolex watches with date complications. A genuine Rolex cyclops provides exactly 2.5x magnification, making the date fill most of the lens and appear very large and clear. Fake Rolex watches often have cyclops lenses with only 1.5x magnification, making the date appear smaller within the lens. Additionally, the genuine cyclops has anti-reflective coating on the inside, making it nearly invisible when viewed from the side.
Where is the serial number on a Rolex?
On Rolex watches made before 2008, the serial number is engraved between the lugs at the 6 o'clock side of the case — you need to remove the bracelet to see it. On post-2008 models, the serial is also engraved on the rehaut (the inner bezel ring) at the 6 o'clock position. The serial number is typically 6-8 characters: a letter followed by 6 digits (1987-2010 models) or a randomized alphanumeric code (2010+ models). Use our free serial number lookup tool to find the production year.
How much does it cost to authenticate a Rolex?
Professional Rolex authentication typically costs $50-$150 for a visual inspection by a certified watchmaker, or $200-$500 for a full inspection that includes opening the caseback to verify the movement. Some online authentication services charge $25-$75 for photo-based assessment, but these are less reliable than in-person inspection. On eBay, watches over $2,000 automatically qualify for the free Authenticity Guarantee program, which includes professional verification before delivery at no extra cost to the buyer.
Do fake Rolex watches tick?
Yes, most fake Rolex watches tick with a visible 'tick-tick' motion, while genuine Rolex watches have a smooth sweeping second hand that moves at 8 beats per second (28,800 vibrations per hour). However, high-end counterfeit 'super clones' now use automatic movements that also sweep smoothly, so this test alone is no longer sufficient. The sweep test should be one of multiple checks, including cyclops magnification, weight, engraving quality, serial number verification, and rehaut inspection.
