DC Rainmaker showed what happens to the watch when you take it past the max depth in his review [1] (using a pressure chamber).

I think your concerns are valid and merited for your very advanced level of diving, but at the same time the vast, vast, vast majority of divers aren't going anywhere near 130 feet. If I were going on a standard "simple" dive to <60 feet, I think I'd be pretty comfortable with just the apple watch ultra, a dumb watch + cheap depth guage and a written back-up plan.

Yes, agree completely. Would be happy to have just this on a 60 foot dive. And will be happy to see it on the wrists of other divers on the boat, as I think it will make them safer vs the status quo. Just wouldn't _buy_ it for that purpose myself, I think there are better options if you research a bit.

Also, I never dive past recreational limits, I'm not a technical diver by any means. I would simply have philosophical concerns about a piece of equipment that could provide accurate information beyond recreational limits, but simply doesn't for "legal" reasons. It probably makes sense to people - "oh they don't want to be liable for giving advice past recreational limits", but other companies seem to have navigated this legal issue and choose to provide accurate information regardless of this arbitrary limit.

As another commenter pointed out, I have no idea what it does past 130 feet, but the disclaimer that it _cannot_ be used past 130 feet, rather than one that says you _shouldn't_ use it past 130 feet, is somewhat concerning to me, even if I don't approach those limits.
