I’m one of those that showers with the watch on a daily basis. I noticed the water repel function on the watch wasn’t getting everything out, especially the soap foam. I discovered that if you put the speaker portion up to your mouth and suck in like you’re playing a harmonica, it clears out everything and gets rid of the muffled sound after exposure to water. Then one final flush out with the built in flush and you’re golden. Sometimes I’ll introdyce some more warm water in there to rinse.
