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 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.
