I would hope that 200 water resistance is waterproof at 75 feet. That and the compass looks good. I finally put a dimestore compass into each of my cars. I was lost on a cloudy rainy day a couple of months ago. That’s not going to happen again.
I wonder if I can get all the junk on a cellphone?
I would hope that 200 water resistance is waterproof at 75 feet. You'll find that most watch manufacturers won't use the term "waterproof" any longer for liability purposes.
The PW 1500 is a tough watch and you can dive with it, but if you were going to do a ton of diving (as opposed to just having the watch submerged now and again) you might want to look at Casio's G-Shock line. I have 8 of them. They're extremely tough and divers love them - especially the Frogman.

I wonder if I can get all the junk on a cellphone? Not sure about apps for barometer, tides, moon phases, altitude thermometer etc., but if you have a GPS enabled phone, there are options for compass and nav tools. There are even some (not many) GPS type apps that only use the phone's GPS funtionality so you don't have to rely on cell tower connection. I have bunch of them loaded into my hacked HTC touch.
Of course for a GPS compass app, you have to actually be moving to get a bearing as opposed to being able to get an azimuth from a stationary position.
That being said, I wouldn't rely on the cellphone GPS for "hardcore" stuff like outdoors, professional, survival or SHTF scenarios. Too many weak links like batteries, connectivity, fragile hardware, elements etc.
The Casio above can go 5 months on a single solar charge without ever getting any kind of light. Normal use in normal light conditions will keep it going for years.
