Quick Checklist: Real vs. Fake Longines
For your convenience, Zuli Watch summarizes the key points to check for a genuine Longines watch in the following table:
9 Detailed Ways to Check for a Genuine Longines Watch From A to Z
To differentiate between a genuine Longines watch and a fake, you need to carefully examine several factors. Here are 9 core steps that the experts at Zuli Watch recommend you take:
1. Check the Serial Number and Reference Number
The Serial Number is a unique identification sequence assigned by Longines to each watch produced. You can find the Serial Number and the Reference Number (product line identifier) engraved on the watch case back.
How to check if a Longines watch is genuine using these numbers:
- Inspect the Engraving Technique: The characters should be extremely sharp, uniform, and consistently deep, usually laser-engraved or finely stamped. Fakes often have shallow, blurry, or incorrect fonts.
- Match the Information: The Serial Number on the watch must completely match the Serial Number printed on the accompanying Warranty Card.
- Verify with the Brand: You can use the “Extract from the Archives” service (for a fee) on the Longines website or contact Longines Customer Service to request verification of the Serial Number. This is a very reliable way to check if a Longines watch is genuine, especially for older models.

Note: High-quality fakes can also counterfeit Serial Numbers, but checking through Longines’ official system is almost the best method.
2. Closely Examine the Dial
The dial of a genuine Longines watch always achieves a near-perfect level of finish. Carefully observe the smallest details on the dial.
The indices and numerals must be applied or printed extremely evenly and sharply, with consistent spacing between them. All printed text (such as “Longines”, “Swiss Made”) should use the correct font, with clean ink that shows no signs of smudging or breaks. If the watch has a date window, the displayed number should be clear and centered within the frame.

3. Evaluate the Watch Hands and Indices
Genuine watch hands are the result of meticulous craftsmanship. They should have a smooth surface, with precisely beveled or cut edges, free from any burrs or minor flaws.
Check the consistency of color and material between the watch hands and the indices. If there is a luminescent coating (Luminova), it should glow evenly and clearly in low-light conditions and maintain a stable brightness (depending on the model). Especially with mechanical watches, the second hand should have a smooth, continuous sweeping motion, not jerky like most cheap quartz movements.
4. Longines Logo – An Icon Impossible to Perfectly Fake
The Longines logo – the winged hourglass – is a crucial detail when checking if a Longines watch is genuine. The genuine logo is always sharp down to the smallest detail, with perfect and balanced proportions of its components (hourglass, wings).
This logo appears in multiple locations: on the Dial, the Crown, the Watch Clasp, and the Case Back. Examine the finishing technique: is the logo laser-engraved, embossed, or just a poorly applied metal sticker? The accompanying “LONGINES” font must also be accurate according to the brand’s design.
5. Inspect the Strap/Bracelet and Buckle/Clasp
The quality of the strap also reflects the class of a genuine Longines watch. Metal bracelets made of Stainless Steel or Gold should feel solid, with tightly and evenly linked segments, and the surface should be finely finished (polished/brushed).
For leather straps, note the meticulous, straight stitching, the genuine leather’s characteristic softness or firmness (depending on the leather type), and the clearly embossed logo or brand name on the inside. The buckle/clasp should operate smoothly and close securely, with the logo on it also finely engraved/stamped. Fakes often have loose straps, cheap materials, and flimsy clasps.

6. Distinguish Through the Box, Papers, and Warranty Card
A genuine Longines watch always comes with complete and high-quality accessories. The Box is made of premium, sturdy materials, with a smooth inner lining and a sharply printed/embossed logo.
The Papers, such as the user manual, are of good print quality with accurate content. The Longines Warranty Card is particularly important: it should be a hard plastic card (newer cards may have a chip or QR code), and the information printed on it (Serial, Reference, dealer name, date of sale) must be clear, without erasures, and must match the information on the watch. It should have the stamp of an authorized dealer. Although accessories can also be faked, it’s difficult for fakes to achieve the same level of finish and quality as the real ones.
7. Pay Attention to the Price – An Important Warning Sign
Price is a factor that cannot be ignored when checking if a Longines watch is genuine. Longines is a Swiss watch brand in the luxury product segment, so their selling prices cannot be “surprisingly cheap.”
If you see a Longines being offered at a significantly lower price than the listed price at authorized dealers, it’s a major red flag indicating a fake or a replica watch.
8. Evaluate the Movement – The Swiss Heart
The watch movement is the soul of a Longines and the area where fakes are hardest to replicate. Although direct inspection of the movement requires opening the case back (which should be done by a technician), you can still make a preliminary assessment.
Longines movements (often developed based on the renowned ETA platforms) have a very high level of finish, with characteristic decorations such as Côtes de Genève stripes, Perlage, meticulously finished bridges, and blued screws. The movement runs stably and accurately. You can listen for the steady, smooth ticking of a mechanical movement. Fakes often use Chinese or low-grade Japanese movements with very crude finishes, lacking the sophisticated decorations of Swiss movements.
