The complete guide to Casio serial number

casio serial number

The Japanese multinational giant Casio is one of the leaders in the production of electronics around the world.

Founded almost 80 years ago, the company has grown from a small office into one of the leading manufacturers.

The company initially became famous for the release of its compact electronic calculators in 1957. Then this device seemed to be the height of perfection.

However, the heyday of Casio is considered to be precisely the period of the 80s-90s of the last century. Then a lot of electronic household items were published, including the famous Casio watches.

THE G-SHOCK DW-500C WAS RELEASED AS THE FIRST MODEL. THIS WAS THE FIRST WATCH IN THE SERIES THAT COULD DIVE TO A DEPTH OF 200 METERS, AND WAS ALSO SHOCKPROOF.

Naturally, more advanced models have come out today. However, collectors hunt for the first of them especially strongly.

Given the high demand for Casio around the world. It is important to understand that you are buying an original item. For this, there is a possibility of authentication.

THE SERIAL NUMBER OF THE WATCH IS TAKEN AS DATA.

How to authenticate Casio G-SHOCK by serial number

The emergence of the G-SHOCK series, the world owes to the Japanese Kikuo Ibe. The master initially set himself the goal of making a watch with which one could do anything.

RELIABILITY WAS SET AS A CRITERION. AS A RESULT, THE WORLD SAW THE DW-500C MODEL, WHICH IS CONSIDERED UNKILLABLE EVEN BY TODAY’S STANDARDS.

To date, a huge number of models and varieties of G-Shock have already been released. All of them can be divided according to the following criteria:

  • Limited edition. This includes models such as the MRG-8000 or Go Green.
  • Original. All of the DW, GM, GW series.
  • Vintage. The first models.
  • Analog. GA series.

The authenticity recognition method is also selected depending on the model.

Basically, it consists of the rules for checking the serial number and decoding it for further comparison.

The original number looks like this: 204A127B

YOU CAN FIND IT ON THE BACK OF THE WATCH, RIGHT ON THE BACK COVER.

Decoding of the number is done according to separate rules:

  • The last letter is taken for the year of production. In the example it is B. It represents 2 periods in which the watch could have been produced. These are 2002 and 2012 models.
  • For the month of production, there are 3 digits in front of the letter of the year. In our case, this is the 127th day of the year. It’s May 7th.
  • From this we get that the G-Shock in question was released on May 7, 2002 or 2012.

A similar test is done for all Solar Casio models.

What else does the serial number say?

AS A RULE, THE FULL SERIAL NUMBER OF JI SHOCKS CONSISTS OF 5 PARTS. DECIPHERING PRECISELY LENDS ITSELF TO THE ONLY WAY THAT IS RESPONSIBLE FOR THE PRODUCTION PERIOD OF THE WATCH.

However, some fans have gone ahead and can confidently state that the rest of the information is also included in the specified code.

  • Abbreviations. DW-are used on digital watches. GA- for G-Shock Atomic models. GL – for G-lide.
  • The second part is digital. Indicates the watch body. It could be anything: 6900, 100,110, etc.
  • The third part. Consists of letters and denotes designs and colors.

Rules for checking the serial number of vintage and analog Casio

For models of a separate series, decoding rules have also been invented.

Other formats of serial numbers are used here and they look like a 6-digit digital code.

This number is easy to decipher, knowing the processing rules. The serial is located on the back of the watch and looks like: 250123 .

Translated, this means that the watch was produced in any of the years 1992, 2002 or 2012. This is indicated by the first digit of the number.

The month of issue is specified by the second digit. In our case, this is May, because it costs 5.

Thus, the watch in question could have been released in May 1992, 2002 or 2012.

IT IS IMPOSSIBLE TO SAY MORE PRECISELY, BECAUSE CASIO DOES NOT HAVE SYSTEMATIZATION IN THE DESIGNATIONS AND THUS ALL WATCHES PRODUCED BY THE MANUFACTURER ARE MARKED.

The authenticity of the watch is ultimately determined by the correct decoding of the serial numbers.

Fakes often do not have the ability to control the codes and any set of symbols that do not correspond to any declared parameters are applied to the cover.
