Can I swim with an Apple Watch showing my heart rate and number of laps simultaneously and not need the iPhone to be nearby? (alien.top)

I want to buy an Apple Watch to track my heart rate and number of laps as I swim, and that's it. The reason I'm choosing the Apple Watch as a fitness tracker is that looking at the graphs on the youtube channel The Quantified Scientist, it looks like it is a lot more accurate than any other wrist-worn device, and a few percentage points off can give a very wrong heart rate reading. My primary phone isn't even an iPhone, I just have one lying around to activate it with. I haven't found any other comparisons that are this in-depth. But it's difficult to understand the software without having one, so I just want to make sure I can swim and look at my wrist and see both my heart rate and number of laps in a 15 yard pool. Also, it looks like every Apple Watch in the last several years has the exact same heart rate sensors so I can just go with the cheapest SE or whatever. Is this correct? Thanks.

Yes you can do this.

I swim pool laps five times per week with my Apple Watch Series 8, previously with a Series 4. The lap counts are accurate. To ensure the accuracy of the heart rate I always tighten my watch band before entering the pool.

On the watch I’ve configured my Pool Swim Workout Metrics to show the following: Time elapsed, Current heart rate, Maximum heart rate, # of laps, Total yards

However without an iPhone you’ll not be able to access all the additional metrics in the Fitness app on the phone.
