It goes like this...

In the year 2002, ROLEX introduced a new security characteristic because counterfeits were getting better and better. It is known as the "laser coronet" in the sapphire crystal. It is located at the lower edge of the crystal at 6 o'clock position and is so small that one can hardly see it with the naked eye. It can be found most simply if you take a look from the opposite side with strong oblique light directed upon the crystal. Only a small mark on the crystal can be seen, which, if viewed with the help of a magnifying loupe, becomes a coronet.

However, the introduction of the laser coronet was done step by step. It was not introduced for all models at the same time. It only started with the Submariner ND, Air King, Explorer and Daytona models. Other models followed with the 'Y' series (in 2002). Some sources reported that the introduction lasted until the end of year 2003, perhaps even until the beginning of year 2004. If you buy a new ROLEX watch now, the laser coronet can be found on every models. Watches manufactured between 2002 and the beginning of 2004 possessed this security characteristic, but depending on the model reference, it may not be present.

With an exchange of the sapphire crystal, this laser coronet is present in the new crystal. The coronet looks however slightly different: Within the laser coronet there is an additional "S" lasered ("s" means changed by service). Although ROLEX introduced the laser coronet as its new security characteristic, it did not take long to find counterfeits with a coronet in the crystal.

At this time, it is "only" a corroded or etched coronet with a thicker, more constant structure as a result. You can recognize these with the naked eye easily and therefore it is quite easy to expose a counterfeit. However, it is only a question of time when better laser coronets occur in the counterfeit market and the laser coronet on its own is no 100% identification of a genuine watch.

I have found an easy way to see the 5 match stick Logo's laser etching. You need a torchlight for example the mini maglite with fresh battery. Shine the light at the 6 O'clock at an angle about45deg from face of the dial. Adjust your angle slowly and you will be able to see the Logo. However if you want to see it more clearly then you need the magnification.

Have fun
