Here are some methods to distinguish between genuine Rolex and fake Rolex:

1.Appearance details:

-Logo: The Rolex logo on a genuine watch is usually sharp, clear, and well-defined. 

The edges are smooth and flawless. In contrast, the logo on a fake watch may be blurry, 

have rough edges, or the proportions may be incorrect.

-Dial: On a genuine Rolex dial, the fonts are uniform, clear, and free of smudges or spelling errors. 

The spacing between the numbers and markers is consistent. 

For example, the date window is precisely cut and the numbers inside are neatly aligned.

Fake dials often have uneven fonts, inconsistent spacing, or even spelling mistakes.

-Hands: The hour, minute, and second hands of a genuine Rolex are precisely made. 

The tips of the hands are carefully finished, and the luminous materials (if applicable) are evenly applied. 

On a fake watch, the hands may be of inferior quality, with crooked or unevenly applied luminous materials.

-Crown: The crown of a genuine Rolex is well-crafted, with clear engravings and a smooth texture. 

It screws in and out smoothly. A fake crown may have rough engravings, a loose fit, or difficulty in operating.

-Bezel: The bezel on a genuine Rolex is tightly fitted, and the numbers or markers on it are clearly engraved 

and evenly spaced. For models with a rotating bezel, it rotates smoothly and has a firm click feeling. 

A fake bezel may be loose, the engravings may be shallow or uneven, and the rotation may be jerky.

2. Material quality:

-Case and bracelet: Genuine Rolex watches are made of high-quality materials such as 904L stainless 

steel (Oyster steel) or precious metals. The case and bracelet have a solid feel, a smooth surface, 

and excellent corrosion resistance. Fake watches often use inferior materials that may feel lighter, 

have a rougher surface, or show signs of corrosion more easily.

-Crystal: Rolex uses sapphire crystal, which is highly scratch-resistant. 

When looking through the crystal of a genuine watch, the view is clear and distortion-free. 

You can also conduct a water droplet test-water droplets will form beads on a genuine 

sapphire crystal rather than spreading out quickly like on a fake crystal.

3. Serial number and model number:

-Engraving style: On a genuine Rolex, the serial number and model number are deeply engraved 

with solid and very fine lines. They are clear and legible, and the numbers will shine at a certain 

angle under light like diamond-cut edges. Fake watches may have numbers that are composed 

of faint dots or have a sandy appearance due to the low-quality marking process.

-Uniqueness: Each genuine Rolex watch has its own unique serial number and model number that 

correspond to its specific model and configuration. If you come across multiple watches with the 

same serial number or model number, they are likely to be fakes.

4. Movement:

Smoothness of the second hand: On a genuine Rolex, the second hand moves in a smooth, 

continuous manner. It seems to glide around the face of the watch. If the second hand ticks along 

jerkily or stutters with each passing second, it is likely a fake. You can also listen closely - a real Rolex 

is very quiet, while a fake one may make a slight ticking sound.

Movement markings: Open the back cover (if possible), and a genuine Rolex movement will be 

engraved with the "Rolex" logo and relevant movement information. The parts are precisely made 

and have a high level of finishing. Fake movements are usually rough and lack the fine craftsmanship of genuine ones.

5. Accessories and packaging:

-Box and certificate: A genuine Rolex comes with a high-quality box and relevant certificates. 

The box is well-made, with the Rolex logo and relevant information printed clearly. 

The certificate contains detailed information about the watch, such as the model, serial number, 

and warranty information. Fake watches often have simple or poorly made packaging, 

and the certificates may be of low quality or lack relevant information.

-Booklets and tags: Genuine Rolex watches come with user manuals, warranty cards, 

and other booklets. These are printed with high quality and contain accurate information. 

Check for any spelling errors, blurry printing, or inconsistencies in the information provided.
