I purchased my Galaxy watch just about one year ago and the sensor just came off and there was sticky gooey stuff all over my wrist. I have never worn it in the shower or swim, I never get it wet, other than sweating during exercise. I tried sticking it back together which didn't last one day. I saw the cover was slipping out from under the watch today. So I started to look for solutions and am very sad to see there are 15 pages of people who have encountered the same problem and Samsung is not standing behind it's product. **So, I searched for sensor cover/adhesive, and found on ebay the adhesive is sold for about $13.

Poor design, I'm very disappointed that Samsung isn't backing this up.
