The appearance of the word "reboot" after submerging it in water, and

@abdullaziz85196 sounds to me like your watch may have taken on some water. I would treat it the same way as I would any other water immersed device.

The very first step I would take is to disassemble your watch. Use these guides Samsung Galaxy Watch Active2 to help you disassemble your smartwatch. Take a close look at all components and connectors. Check for major corrosion, evaluate the pins in the connectors etc,. If you need to use water to clean any gross contamination, use sterile water. Take a look at all connectors as well as cable ends. Once you got the gross contamination cleaned, use 90%+ isopropyl alcohol and clean your parts some more. For a proper cleaning, use this guide. It was written for an Apple iPhone 3G but it is still pertinent to your watch as well. I can not stress the importance of a good cleaning enough, so do it over and over while replacing the alcohol after each cleaning. Do not use compressed air for the cleaning since that can drive liquid as well as corrosion particles into areas that will cause trouble later on. Also, you do not need to leave the parts to dry for a day. Isopropyl alcohol in the higher concentration will evaporate quickly and dissipate the water. The importance here is the cleaning. It would of course be best to get it professionally cleaned Do not forget to replace the battery. This is a must and not an option. It will fail if you do not take care of it now. After that, reassemble your smartwatch and re-evaluate.
