Support find model and serial numbers for Watches

 

The example shown in this picture illustrates where to find the module number and model number for a typical Casio watch. As you will be able to see, they are both embossed on the rear plate of the watch. The module number is numeric and will normally be 3 or 4 digits located inside a rectangular box. The model number consists of a combination of letters and numbers which are hyphenated.
