I am going with a Shearwater Perdix 2.
Another option would be to get the Apple Watch Ultra at first, considering that you're already an Apple guy. The AWU only costs $270 more than an equivalent non-ultra, and it also adds lots of cool “normal” features.
That's a fraction of the cost of the Perdix, and the AWU covers you to 130' (actually to 144' - when you ascend back to 130', it resumes normal readouts after pausing between 130'-144').
There are other advantages… You keep the AWU as a backup device, after you add a Perdix. That way, you get extra features like phone calls & maps at the surface, alongside the Perdix as main DC. And you get extra time to react to upcoming dive computer advances before committing the major Perdix cash.
