Second Hand Ticking
Rolex watches use high-quality mechanical movements. The movements are notoriously smooth. Rolex watches tick four to six times every second. This created an illusion that the hands are sliding. An ordinary watch ticks every second. So, if you see a Rolex ticking like a common quartz movement, it is likely that the watch is fake. But this might not be true. Rolex did make a few watches with quartz movements.
Weight is a good indicator of the authenticity of a Rolex model. Rolex watches are manufactured using heavy metals. Even a gorgeous fake will be unable to replicate its weight. The solid feel of a Rolex watch is not easy to achieve.
Details are not neglected in manufacturing a Rolex. The serial number of a Rolex watch is stamped with a lot of attention. Original Rolex watches flaunt fine details such as a diamond-cut edge. The serial number of a fake Rolex watch will be engraved cheaply. The fake watch will have a cheap stamp, or the quality of the acid etching will be too poor. Most of the time, the fake watches do not have a serial number at all. This is an easy giveaway.
Every original model has the word "Rolex" engraved somewhere on it. The inside of a Rolex model is beautiful. You will be able to tell by looking at it if the model is a generic one or not. Moreover, if you open the model's back and see anything remotely resembling quartz movement, you know it's fake.
The appearance of an original Rolex is pristine. If you notice any streaks or variable fonts, or spaces between words, know it's not authentic. Furthermore, a fake Rolex will miss the typical Rolex crown. Original Rolex models also have a cyclops magnifying lens that magnifies the date 2.5 times. If the Cyclops lens is absent, it's an immediate red flag.
