What's a good way to keep track of the time at a water park?

I want to make sure I reapply sunscreen every 1-2 hours, but I don't want to carry my phone or wear a watch on my wrist. I'm thinking it would be ideal to have some kind of super light waterproof pocket watch that I can attach to my swim trunks or something. But I don't know if such a thing exists. How do you guys normally check the time when you're at a water park?
Yeah, it really annoys me that at the water park I usually go to (not the best, but the closest one to me) there aren't any clocks around, even in the food stalls or places like that. Fortunately, when I look around I can usually find someone wearing a watch or looking at a phone that I can ask.
I use the hand trick with the sun.
4 fingers between the sun and the horizon is about an hour. From time to time, I just take a measurement.
For every 4 fingers of additional height until noon is an hour, from every 4 fingers of less height after noon is an hour.
Edit: One of the best times to check if when you're at the top of a water slide tower, since they usually give you a nice view of the horizon.
Not to be that guy, but why don't you want to wear a watch? This is like one of the prime use cases for a waterproof wrist watch
