Out of curiosity, what do you actually DO with all the data those things collect?
I can't speak for the OP, but for me, as a late adult onset swimmer, the data gives a nice history of my actual performance over time. I find my memory isn't that reliable as to my actual performance at different stages of my swimming progress, when I look at the data I can see where I actually was making progress and where I stalled out. I can experiment with my technique and have an objective record to review afterwards of what worked and what didn't. I also always breathe to the same side of the pool so that I'm working my strong and weak side equally, and I always review my time on the lengths to see if I'm closing the gap between my weak side and strong side.
One of the big attractions initially for me was not losing count of my laps and counting my yardage, but I will say as I've gotten more experienced with my swimming, structuring workouts, and watching the pace clock I find I rarely lose track of what I'm doing any more.
For me the watch is generally pretty accurate as to my yardage but I do see some occasional glitches on individual lengths where the watch didn't quite get the timing of the turn right.
I would think the data would be pretty useful for a coach dealing with a remote athlete.
I know the fishes think these watches are for dorks, and well, maybe I'm a dork but so what. If I was a longtime fish with mature technique, a stable level of fitness, and a great feel for varying timed intervals with the pace clock, I doubt I'd bother with the watch.
Edit: Forgot to mention that I swim at a pool in the summer that has no pace clock and the watch is nice to have in that context.
