Re: Casio SeaPathFinder Tide Graph
Look in Surfing stores, or do a search for surf watches, or tide (tracker) watches. They've been making them for surfers, literally for decades.
Also, while I know squat about smart phones, I'm sure there are apps with these functions for them.
That, & just go to some of the big name (low to mid range) watch company websites, & pull up a chart of the listed features per model. And or do a search based on what you need the watch to do.
