Rolex serial numbers and model numbers
Rolex serial numbers are very useful in determining the approximate age of your Rolex timepiece. When combined with the bracelet clasp code, Rolex serial numbers can also be used to determine the originality of the bracelet. There are two sets of numbers generally found on Rolex watches. These are the model numbers and the serial numbers. These numbers are generally found between the lugs or horns on the watch, so the bracelet or strap must usually be removed to see them properly. The serial number can be found between the lugs at the 6 O'clock position and the case reference or model number between the lugs at the 12 O'clock position. These numbers are also found on the inside and outside of the case backs on some of the vintage Rolex models or in a combination of both.
What your dial is telling you
The information on the dial actually tells the story of the watch. Firstly, the ‘Rolex’ name and the five pointed crown at the top of the dial clearly shows that it is a genuine Rolex, with its well-known symbol that represents wealth, royalty, and success. The second line often states ‘Oyster Perpetual. Secondly, you may have noticed on the dial of your watch the writing ‘Superlative Chronometer’ and ‘Officially Certified.’ This means that your timepiece has been certified by COSC for accuracy. Many Swiss Rolex Replica watches carry this certification, but as a company, Rolex submits the highest number of watches for COSC certification over anyone else in the world and this tells you just how well-made your watch is. Thirdly, your watch should have the words ‘Swiss’ or ‘Swiss Made’ (or something similar) at the bottom of the dial and this means that the watch’s movement is Swiss. Fourthly, if the watch were manual, the word ‘perpetual’ would not be present. If your watch has an automatic date mechanism, the dial will say ‘Oyster Perpetual Date.’ Lastly, the dial will also sport the model name, either above or below the hands.
