A few months ago I owned an iWatch 3. That Apple thing is waterproof, so I went swimming with it, went to the sauna, again swimming and so on. Never had problems with it.
In the manual it was discouraged to go swimming with the watch. Because of the standaard swimming app, I gave it a try and I succeeded.

Today back to Samsung and I'm wearing a Gear S3 frontier these days. The same story in the manual: waterproof, but don't swim with it and don't go into a sauna.

Is the Gear S3 less waterproof compared with the iWatch, or can I take the risk without breaking my new Gear S3?
