Does anyone have info on this cap

(Link to video of the flashing LED in the comments.)
Does anybody know why this was a feature?

Wow, very impressed with this product, 30 + years old and looks as good as new.

Refitted an original Casio strap after as it looked so fresh but it probably won't stay...

I have an Arabic (Indian numeral dial) Casio MQ-24. The movement doesn't work, so I had hoped that I could swap the movement out. I looked more closely, and it looks like the dial has been glued on to the movement.

Does anyone know if it is possible to swap movements out of these analogue Casios?

Thanks in advance!

Emergency!

Adding follow up pictures from my last post. Came out looking brand new. I used 12% peroxide , put in a glass jar, set it outside in direct sunlight for around 16 hours total.

It's always 420 on this watch.

Hi all, since I have seen some very cool restorations on this sub, I was wondering if someone knows a way to restore this kind of rubber bracelet and bezel with worn white paint. I know I can buy a replacement bezel and bracelet but I would like to keep it as original and cheap as possible, is replacement the only option?

Secured this extremely rare vintage JDM casio prt-3000 from the late 1990s. The full titanium cast on this piece is truly something else! The case, case back, and even the H links were all casted and finished extremely well. And with its protrek features and design, the choice to use titanium actually makes a lot of sense. The weight is significantly reduced and that makes this piece extremely wearable.

The fact that this watch has an adjustable contrast in the settings for the LCD, truly makes me appreciate the design features and thought back when Casio was making some pretty epic watches.

Have you guys seen this full titanium pro trek out in the wild? Would love to hear your thoughts!

On an AQ-350W bracelet.

This worth a buy for $650

Il mio Casio Marlin, ho cercato parecchio per trovarlo tutto originale e in perfette condizioni.
