Diagnostics for GWM500

Some people describe these as "hidden features" on their G-Shock watches. That may be accurate since there is no mention of these diagnostic functions in the official owner's manual. By pressing multiple buttons in different combinations it's possible to bring up diagnostic functions and/or information that isn't normally accessed. These same button combinations may work on most other G-Shock watches.
By accessing these diagnostic functions, the user can test that the LCD segments are all visible, that the automatic backlight "tilt switch" is working properly and that the "Tough Solar" solar cell is reacting to lighting changes the way it should. These diagnostics are not very important in everyday use but maybe, someday, they will be useful just to make sure your watch is working right.
In this video I demonstrate accessing these diagnostic functions on the GW-M530 and GW-M500 and I also show you several different versions of that watch. The watches in this video all use Casio's Module 3405.

Great information Greg thanks for posting. I just got the watch but the date is wrong and the watch is not synchronizing.

3179 is base module number with different display layout depending on the watch model. Same module number display on gw6900, gw5000, gw-m5610.

I couldn’t get it to go into the mode where you could see where the signal is coming from Greg

Hola Greg me encanta tu canal, me ha ayudado mucho a conocer más sobre los relojes Casio, tengo una pregunta. Tengo un Casio con el de ti vídeo, pero nunca ha cargado hasta "H" a que se debe? Lo adquirí hace unas semanas. Saludos

Just picked up this watch for work, I can't get anything to work on the watch. No buttons work. Not sure if you had an issue setting it up after purchase?

Hi Greg I love your 3405 collection. I’m looking all over for the green tint version (I forget the name) is there anyone you know who has it? If not would you be willing to sell? Thanks

It's from the fire package in 2015 (I believe). I have the green anidigi model from the fire package of that year. Love the green on that one, been looking myself for a few months now.
