|Sources: Amazon, ManufacturerApple Watch Ultra 2 vs Samsung Galaxy Watch6 Classic (47mm, Bluetooth)
The Apple Watch Ultra 2 is the flagship option here, boasting a stunning 3,000-nit display that crushes the Samsung Galaxy Watch6 Classic's 480-nit screen. If outdoor visibility is essential for you, the Ultra 2's screen brightness makes it a no-brainer for outdoor enthusiasts. The Ultra 2's bulkiness at 2.17 oz may feel cumbersome for smaller wrists. Meanwhile, the Galaxy Watch6 Classic offers a lighter 2.08 oz build and a battery that lasts up to 40 hours, making it more practical for everyday wear. In real-world usage, the Ultra 2's impressive battery life of 36 hours in normal mode means you can go longer between charges, but it’s worth considering personal comfort and style.
