Taking A $15 Casio F91W 5,000 Meters Underwater

Brands like Rolex and Omega will often tout their deepsea capabilities with the Rolex Deepsea Challenge rated to 11,000 meters (36,090 feet) and the Omega Ultra Deep coming in at a lesser but still ridiculous 6,000 meters (20,000 feet) of theoretical water resistance. But what about a cheap Casio often associated with terrorists and hipsters? With around $15 and some engineering know-how, can an affordable watch also venture into the deep ocean?

    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…

      The 91fw is still made to this day though. I have 3 of the things myself. My favourite watch to wear

        Oh, well then. I just seen a quick mention of a year in the late 80’s. Guessing they’re still made just as good?

    I read it as “casino” and was very intrigued on many levels.

    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.

    11,000 meters

    6,000 meters

    5,000 meters

    I’m not entirely sure of the application here.

    https://en.wikipedia.org/wiki/Deep_diving

    The deepest dive listed here is:

    534 m (1,752 ft): COMEX Hydra 8 dives on hydreliox (February 1988 offshore Marseille, France).[2][4][10]

    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.

        Well yeah, the straps are junk. Zulu or NATO strap and you’re set.

        *incompletely indestructible, that is if you count the band as the watch. There’s metal bands available if you want it to be tougher
