ToggleKnowing how to distinguish a genuine Cartier watch from a fake is crucial for any prospective buyer or collector. This guide provides comprehensive steps to identify authentic Cartier watches, ensuring you make a secure investment.
Cartier’s Hallmarks of Authenticity
1. Examine the Overall Craftsmanship
A real Cartier watch exudes quality. The first step is to look at the overall craftsmanship of the watch. Authentic Cartier watches are crafted with a high level of detail and finish. Examine the watch for any signs of poor finishing, uneven spacing, misaligned elements, or spelling mistakes on the watch face or back. Genuine Cartier watches will have flawless lettering without any errors.
2. Check the Watch Case and Serial Numbers
Every Cartier watch has a serial number engraved on the back of the watch case. This number is unique to each piece and can be used to verify its authenticity. The serial number consists of two letters followed by four digits. If you’re considering purchasing a Cartier watch, ask for the serial number and verify its authenticity by contacting a Cartier store or an authorised retailer.

3. Quality of the Glass
Cartier uses sapphire crystal for the watch glass on all its models. Sapphire crystal is extremely hard to scratch, so a genuine Cartier watch’s glass should be pristine, unless it has been roughly treated. You can test the glass by dropping a few drops of water on it; on a real Cartier, the water will pool together due to the tension, whereas on fake glass, the water will spread.

4. Movements and Mechanisms
The movement, which is the internal mechanism of the watch, is also a tell-tale sign. Cartier typically uses Swiss-made movements, which are smooth and precise. A stuttering or unusually loud movement is a clear indicator of a fake. Furthermore, many genuine Cartier watches have an automatic movement, which means they self-wind with the motion of the wearer’s arm. If the watch is described as automatic but still requires a battery, it is likely not genuine.
5. The Weight of the Watch
Authentic Cartier watches are made with high-quality materials which contribute to their weight. A genuine Cartier will feel solid and heavy in the hand. In contrast, a counterfeit might feel lighter due to the use of inferior materials.
Key Features to Inspect
1. Logo and Font Consistency
The Cartier logo is usually a clear indicator of authenticity. The Cartier logo should be crisp and distinct, without signs of blurring or disproportion. The font used is also specific and consistent across their range. Any deviation from this could indicate a counterfeit.
2. Crown and Case Back
The crown of a genuine Cartier watch should feature a gemstone, typically a sapphire that is neatly embedded into the crown. Counterfeits often have a glued-on gemstone that looks unconvincing. Additionally, the case back of the watch should be perfectly flush with the watch and should feature no signs of poor craftsmanship, such as rough edges or visible adhesive.

3. Metal Quality and Engravings
Cartier watches are made from precious metals and fine alloys. The colour of the metal should not show signs of fading or chipping. Engravings on a genuine Cartier watch will be precise and sharp. In contrast, engravings on counterfeit pieces might be shallow, uneven, or fuzzy.
Places to Purchase and Verifying Authenticity
1. Buy from Authorised Dealers
It is safest to purchase a Cartier watch from an authorised dealer to ensure its authenticity. Authorised dealers are directly supplied by Cartier and guarantee the authenticity of the watches they sell.
2. Verification Through Professional Services
If purchasing a Cartier watch from a secondary source, it is advisable to have it verified by a professional. Many reputable watch dealers and jewellers offer authentication services for a fee. They will examine the physical and operational characteristics of the watch against Cartier’s standards.
Sealing Genuine Luxury
Purchasing an authentic Cartier watch is about more than just owning a luxury timepiece; it’s about making an investment in craftsmanship and heritage. By following the detailed steps above to verify the authenticity of a Cartier watch, you can ensure that your investment is both genuine and worthwhile. Remember, when in doubt, consult directly with Cartier or an authorised dealer for peace of mind.

What should I do if my Cartier watch glass scratches?
