Do Casio Watches Have Serial Numbers? (Things To Know)

The serial number is a one-of-a-kind identification for your watch’s category, model year, and manufacturing run number. Thus, some products, especially from reputable brands, come with a serial number to quickly check the service history and whether or not the item has been reported stolen.

However, the serial number isn’t available for all timepieces. Therefore, some people who own a Casio or intend to buy one might be asking “Do Casio watches have serial numbers?”. Don’t worry! The information you need is all included in this article.

Do Casio Watches Have Serial Numbers?

Generally, the bulk of Casio watches do not have serial numbers. Usually, only their high-end segment has a serial number, whereas some others contain batch code.

For example, some premium product lines, including G-Shock models, feature a serial number that is 6 characters long on the rear. The second character can be an O, N, or D, but the remaining are all numbers. Meanwhile, solar-powered Casio watches include a batch code. It is 8 characters long and contains both numerals and letters, with the final character always a letter.

However, if you can’t find either serial number or batch code on your Casio, the watch module will work for narrowing down the date of your watch. In addition, this code is in a box on the case’s rear. Thus, for any of these codes, you do not need to open the watch.

What Is The Model Number Of Casio Watch?

While the serial numbers aren’t usually available, all Casio watches are engraved with the model and module number. As a result, these codes are essential for buyers to know more about their timepieces to avoid a wrong purchase.

The module number consists of three or four numbers on the back of the watch case. Besides, the model number is located to the right of the module number. It is generally composed of three main parts separated by dashes. However, the model number may only have two parts in some cases.

In this section, we will look through the meaning of 3 primary parts from the left to the right of the model number:
