AF factory vs ZF factory Longines Concas, what is the difference? An expert will tell you the truth!

As a classic sports watch, the Longines Concas series has always been favored by watch enthusiasts for its elegant design and practical functions. However, the price of original Longines Concas is relatively high, which makes many watch lovers turn their attention to the replica watch market. Among the many replica brands, Longines Concas from AF factory and ZF factory are undoubtedly popular choices. But what exactly is the difference between the two? Which one is more worth buying? Today we will conduct a detailed comparative analysis in terms of appearance, material, detail processing, etc.

1. Overall appearance: highly similar, details can be seen in the real book

Judging from the overall appearance, the Longines Concas from the AF factory and the ZF factory are almost identical. The design styles of the dial, case and strap are exactly the same. The diameter of both watches is 41 mm, the thickness is about 12 mm, and the weight remains at about 183 grams. There is almost no difference in parameters. However, after careful observation, we can find that there are still some differences in the details of the two.

2. Material comparison: There is no difference between top configurations

Whether it is AF factory or ZF factory, Longines Concas uses sapphire crystal mirror, Seagull 2824 movement and 316L fine steel. These configurations are currently standard for top replica watches, ensuring the durability and accuracy of the watch. Therefore, in terms of materials, there is no obvious difference between the two factories.

3. Color contrast: The gray plate has the most significant difference

In terms of color reproduction, there is not much difference between the black and blue versions of the two watches, but there is a more obvious difference in the gray plate version. The gray of the AF factory is lighter and closer to the original color, while the gray of the ZF factory appears darker. For watch lovers who pursue a high degree of restoration, the AF factory’s gray plate may be more attractive.

4. Bezel comparison: AF factory is closer to the original version

There are tooth patterns on the side of the bezel, and the AF factory performed even better on this detail. Through actual measurement, it was found that the bezel of the AF factory is slightly thicker than that of the ZF factory, which is more consistent with the original design. Therefore, in terms of the restoration of the bezel, the AF factory is slightly better.

5. Strap and buckle: AF factory has stronger texture

The comparison of the strap and buckle is the biggest difference between the two watches. First of all, in terms of watch buckle engraving, the frosted texture of the AF factory is better, the engraving is clear and the spacing is reasonable; while the polishing treatment of the ZF factory appears rough and thin, lacking a sense of luxury. Secondly, in terms of the opening and closing feel of the buckle, the AF factory is smoother, while the ZF factory is slightly stiffer. In addition, the “XG” engraving on the clasp of the AF factory is fully present, while this detail is missing from the ZF factory.

6. Summary: AF factory is better and more cost-effective

Taken together, the AF factory’s Longines Concas is closer to the original in terms of detail processing and texture performance, especially in key points such as bezel thickness, buckle engraving and opening and closing feel. Although the price of the two is the same, the overall quality of the AF factory is obviously better. If you are pursuing a higher degree of restoration and wearing experience, AF factory is undoubtedly a better choice.
