We already understood a couple of details about Samsungs Galaxy Watch 3, however a brand-new video from TechTalkTV (by means of The Verge and SamMobile) appears to expose most whatever else you require to know. It also exposes a physical turning dial like the Galaxy Watch, but unlike the virtual touch dial on the Galaxy Watch Active 2.
According to the video, the Galaxy Watch 3 (there is no Galaxy Watch 2) has IP68 water resistance and a 5 ATM ranking, so you can dive to 50 meters (164 feet) for approximately 10 minutes. It also loads high blood pressure, heart rate and ECG sensors. Any video can be faked, obviously, so take the images with a small bit of salt.
