Modified by oil-filling, though.

Yeah but.. it’s just the way of gases and liquids under pressure. Even if you could sustain the pressure with gas it would be an unnecessary implosion risk if it’s pierced. As long as it still functions fully including on the surface, I wouldn’t qualify that as cheating. More like us biological weaklings who need ~1atm can be cheap and skip the liquid/resin because if we accidentally end up in space or the deep sea we generally have bigger problems than checking the time.

  easy solution: fill yourself with oil before diving. checkmate, nation-state navies

    I've read that it's possible to breathe oxygenated liquid perfluorocarbons, but something about the idea is just terrifying to me. I think it's the "fluoro" bit specifically that scares me, even moreso than the "liquid" part.

      Humans can't really "breathe" oxygenated liquid. Our diaphragms aren't strong enough to move sufficient liquid in and out of the lungs, so it can only work with external mechanical ventilation. This is occasionally used as a salvage therapy for patients hospitalized in critical care but is totally impractical and unsafe for any sort of diving. In the real world outside of sci-fi movies, any human diving much deeper than about 0.5km will have to be done in an an atmospheric diving suit.

      Based on a video of a mouse I saw, I'd describe perfluorocarbon breathing more as you can drown in it and not die.. it definitely did not look pleasant.

I think it would have been interesting to send two down, one oil-filled and one not and see at what depths they break (or don't). The watches are cheap enough that destroying one isn't much of a loss.
