Familiarity: I've put it through the wringer
This watch is not actually water resistant and the manufacturer says it is only designed to withstand splashing. "This watch is designed to withstand light splashing as in washing hands, getting caught in the rain, etc. However it is not going to last if exposed to water, or submersed in water for long periods of time." I cannot even shower with mine without the watch fogging and the occasional full lock up requiring drying it near my water heater.
That said, it does always come back to life, and is otherwise very reliable. Just have to remember to take it off before a swim.
