Casio watch manuals by module number – all PDF guides

29.08.2026


The module number is the small four-digit number in a rectangle on the case back of every Casio. It is not the model reference; it is the module that determines which manual applies to your watch. The same module is often used in dozens of models with different cases and colours, so below we have arranged the official manuals by module and listed the models from the CLASSIC catalogue that use it.

How to find the manual for your Casio

  1. Turn the watch over and find the four-digit number in the rectangle on the case back (for example 5081, 3502, 5479).
  2. Find the same number in the list below. For most modules there is a manual in English with our models, and next to it the original Casio PDF.
  3. If your module is missing here, write to us at office@classicwatches.bg with the model and module and we will send it to you.

On every Casio product page at CLASSIC the link to the manual sits below the specifications table.
