Smart ring water resistance explained
What IP68, 5 ATM and 10 ATM do—and do not—promise.
Definition
IP ratings and ATM claims come from controlled tests; they are not unlimited depth guarantees.
Bottom line
Follow exact maker instructions. Do not assume a 100 m claim permits diving, hot tubs, detergents or high-pressure water.
Different standards
IP focuses on ingress under set conditions; ATM describes pressure resistance. Marketing shorthand can hide duration limits.
After water
Rinse salt or chemicals if instructed, dry ring and finger, and never charge wet hardware.
