The Galaxy Watch 8 is 11% thinner than the Watch 7, and thanks to the Cushion Design and Dynamic Lug system, it offers a more secure fit for improvedย health and fitness tracking accuracy.
Re-engineering the Galaxy Watch 8โs internal structure also led to a slight increase in battery capacity. The 40 and 44mm variants are powered by 325mAh and 435mAh batteries as opposed to 300mAh and 425mAh.
The circular display is gorgeous and, once again, upgraded. Itโs a Super AMOLED panel that is 50% brighter than the Watch 7โs. It boasts a peak brightness of 3,000 nits instead of 2,000 nits, making the Watch 8 much easier to use in direct sunlight.
The Classic formula is beloved by many Samsung smartwatch fans, and now itโs making a return. The Galaxy Watch 8 Classic has the iconic rotating physical bezel powered by a 3D Hall Sensor. The bezel surrounds the circular screen atop the Cushion Design body.

This time, rather than offering two sizes, the new Galaxy Watch 8 Classic is available only in a 46mm size. It, too, has a larger battery of 445mAh compared to the last Classic (6) model, and the screen is just as bright as the Ultraโs, topping 3,000 nits.
