Massive leak reveals key Samsung Galaxy Watch 3 specs and features

The OG Galaxy Watch in 42 and 46mm sizes
The Galaxy Watch 2 is… not here, and neither is the Galaxy Watch Active 3, but Samsung looks set to unveil the Galaxy Watch 3 soon as sort of a combined sequel to both the 2018-released Galaxy Watch and last fall’s Galaxy Watch Active 2.
Screen sizes, overall dimensions, and battery capacity
Exactly like its aforementioned forerunners, the Galaxy Watch 3 has been widely expected for a while now to come in two different case sizes. Well, today we can add the display diagonals and device measurements into the equation to make several important observations you might want to consider before deciding what Samsung smartwatch you should buy later this summer.
The Galaxy Watch 3 and Watch Active 2 should have a lot in common in terms of battery life too, although there are no words on what processor will be found under the hood of the upcoming Tizen-powered device. This could always improve the energy efficiency of the 247 and 340mAh batteries on the 41 and 45mm Galaxy Watch 3 versions respectively.
These are smaller than what the chunky Galaxy Watch offers, but identical to the cell sizes on the 40 and 44mm Watch Active 2 respectively.
Sensors and other features
ECG functionality in action on the Galaxy Watch Active 2… in Korea
We have no idea if the company is working on any additional health features for the Galaxy Watch 3, but for what it’s worth, the memory and storage counts are expected to jump from 768MB and 4GB respectively to 1 and 8 gigs even on Bluetooth-only variants.
Optional LTE support is naturally in the cards, as are standard GPS functionality, IP68 water resistance, MIL-STD-810G endurance, and Gorilla Glass DX screen protection. Interestingly, SamMobile’s latest report mentions nothing about an aluminum model, with stainless steel and titanium seemingly tipped as the only build material options.
