Samsung Galaxy Watch 3 review: specs and price
The Samsung Galaxy Watch 3 is a highly customizable smartwatch with tens of thousands of different faces and wristbands to choose from. The battery easily lasts the day and can be fully charged in a couple of hours. Plus, if you run low on battery, you can wirelessly charge it from a compatible Galaxy smartphone with PowerShare.
It has tons of great features that many smartwatches don’t have, such as ECG technology to monitor your heart’s electrical activity, blood oxygenation tracking, and fall detection. As well as that, you get all of the standard fitness tracking you’d expect, including heart rate monitoring, hydration tracking, and sleep tracking.
All of this information is delivered to you by a gorgeous 1.2” Super AMOLED display, which features deep blacks and vibrant colors. If you’re looking for a stylish GPS smartwatch with premium features (and without the premium price), the Galaxy Watch 3 is a great choice.

Ótimo para quem pratica um exercício físico diario, estuda e/ou trabalha. Excelente resistência, é confortável e seus sensores são muito bons. Não recomendo para a prática de ciclismo acima de 6 horas, pois a bateria não aguenta Perdeu sinal algumas vezes do GPS, mostrando uma linha de um ponto a outro.

Excelente en todo excepto la batería porque difícilmente llegas a 2 días completos y si activas el Always On Display menos. Lo que más pierdes es que si sueles cargarlo por la noche pues tendrás tu análisis de sueño un día si y al otro no.
