Answers to the most common questions about how AskMyWatch works and Casio watches.
AskMyWatch is a free online assistant powered by artificial intelligence. It automatically loads the official Casio manual for your module number and answers your questions in plain language. No account needed.
The module number is a 3 or 4 digit code that identifies the type of movement in your Casio watch. It is engraved on the case back, framed in a small rectangle. Multiple different watch models can share the same module number, as it identifies the mechanism, not the external design.
Flip your watch over. On the case back, you'll see engraved inscriptions. The module number is the 3 or 4 digit code framed in a rectangle. It's present on all Casio watches, regardless of the range: G-Shock, Baby-G, Pro Trek, Edifice, Vintage, or Oceanus.
AskMyWatch covers all Casio ranges that have an official manual: G-Shock, Baby-G, Pro Trek, Edifice, Casio Vintage (Collection), Oceanus, and standard Casio. If the PDF manual exists for your module, the AI will automatically load it.
Yes, AskMyWatch is entirely free. No account, no sign-up, no credit card. Just enter your module number and ask your questions. A daily quota applies to ensure fair access for everyone.
No. AskMyWatch is an independent project. It is not affiliated with, sponsored by, or endorsed by Casio Computer Co., Ltd. The manuals used are official documents that Casio makes freely available on their website.
If no manual is available for your module number, the AI will switch to general assistance mode. It will ask you about your watch (brand, model, what you're trying to do) and try to help with its general Casio watch knowledge.
Yes, this is very common. The module number identifies the electronic movement, not the case or design. Two watches that look completely different but share the same module will have exactly the same functions and manual.
Casio assigns a 3 or 4 digit module number to each type of electronic movement. Available features — alarms, stopwatch, world time, backlight, sensors — depend on the module. The same module can be used in multiple different watch references.
The manuals are official PDF documents published by Casio. Casio makes their watch manuals freely available on their official website, organized by module number. AskMyWatch downloads and analyzes these documents to answer your questions.
Your current conversation is stored temporarily in your browser to let you resume if you return to the same module. It is cleared when you change modules or click "Clear conversation". No conversations are stored server-side.
