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?
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.
I think this might be what you want: https://www.amazon.com/Waterproof-Stopwatch-ANTEQI-Function-Calendar/dp/B0BZGTDSRT/ref=sr_1_6?crid=2KEZXYCGFMX2S&keywords=waterproof+timer&qid=1687566752&sprefix=1tb+micro%2Caps%2C254&sr=8-6
But if you search amazon for “waterproof timer”, there are other options.
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
Maybe every other ride? I just feel it out, does it feel like an hour? Then sun cream. It’s not like putting it on too often is an issue.
Make sure it’s waterproof though. If not then you need to reapply after every time you go in the water.
If you have a closeable pocket in your swimpants then take a small tool and take your watch off its wrist straps. Put that in the pocket and you will be able to check the time whenever you want.
Good idea!
