The user manual to your Casio Royale / Casio AE1200
The standard manual is filled with small prints and technical terms. Here’s our take of the simplified instructions to get you running quickly with your new watch. While this post is intended for the Casio AE-1200, a.k.a. the Casio Royale, the step by step guide is also applicable to any Casio watch sharing the module 3299 and 3198 (The world-time module).
If there’s anything you need that I didn’t cover, please leave it in the comments below and I’ll continue to update and make improvements to this page.
