I wish the article didn’t skip the part about how they filled it up with mineral oil that sounds cool.
They do mention there’s lots of guides. I couldn’t find a wikihow, but here’s a forum link https://www.thewatchsite.com/threads/superlative-oil-filled-f-91wthe-making-of-the-superlative-oil-filled-casio-f-91.8273/

Back when stuff was mostly built to last. When pride still existed. Now the alarm function is behind an app and subscription…

I’m very active outdoors and have 6 Casios, one like the model here. I’d shit kittens if one actually leaked.
They’re $10-$100 on eBay. Got one for $20 that shows the moon phase and tides.
I read it as “casino” and was very intrigued on many levels.
11,000 meters

The deepest dive listed here is:

I guess you could build a submersible and put the watch on an arm outside the submersible or something.
Not that it’s much closer to those insane watch depth limits, but saturation driving had a record of 700 meters or so.
I used to have one of those. Absolutely indestructible
