The differences between an original and a fake Rolex aren't always obvious but with a few simple instructions you can tell if a Rolex is an original or a fake.
1) Look for a smooth movement of the second hand. Rolex watches feature a seconds hand that moves smoothly over the watch face instead of moving from one place to the next. Look at the second hand on your watch carefully and see if it follows the entire circle around the watch? Or does it increase and decrease its speed or interrupt? If the seconds hand is moving in any way other than a smooth chain, then you are not wearing an original Rolex watch.
2) Look for the "zoom lens" date. Rolex watches feature a window or small dial that displays the date. It is usually located on the right side of the watch face (the location of the watch to make it easier to read the dial some Rolex watches include a magnifying glass (sometimes called "scolops") in the form of a glass over the dial. This part is difficult to imitate so many fake Rolex watches will have something on it. It appears on the magnification plate but look closely, it will actually be a normal bottle.If the magnification plate above the date dial doesn't seem to really magnify the number, you may have a fake Rolex.
3) Release the adjust knob and return the knob to change the date, it should change to the previous date when you move 6 threads, not at 12. This is impossible to replicate. If not, then they are most likely a imitation and not the original.
4) I feel suspicious. Authentic Rolex watches are made of metal and crystal and therefore are heavy. If you feel that a Rolex is suspiciously light, it may not be of high quality or it may be without some of the precious metals that are used in some Rolex models that may be substandard.
5) Test the watch's water resistance. One sure way to determine if a Rolex watch is an original or a replica is to test its water resistance. All Rolex watches are crafted to perfection; If the watch leaks even a little water, it is not original. To test the water resistance, fill a beaker with water and make sure the stem/screw is tight, plunge it into the beaker for several seconds and remove. The watch should work perfectly without seeing any water inside with the hands. If you see any water, it's a replica watch.
6) The greatest value of Rolex watches is in the machine that converts kinetic energy into mechanical, so the seconds hands will move when you move the watch or wear it, and when you do not use the watch and with the passage of a day, the watch will stop working, while the imitation watch has a normal battery inside and not a machine.
When all else fails, compare your watch to the original. If you are not sure that it is a genuine Rolex, a comparison can help you ascertain how a watch should look by looking at the diameter of the dial or the thickness of the strap. The Rolex website contains a catalog of all watches produced by Rolex with many pictures of each. Find the exact model of your watch on the Rolex website and compare what the two watches look like. Pay close attention to the disc; Is everything where it should be? Does your watch have any extra dial like dial like cut time or date, is it in the right place? Are all inscriptions the same? Are the fonts and characters the same?
