Single-Band Wi-Fi
It’s perhaps a small thing, but the new Apple Watch Series 6 actually supports dual-band Wi-Fi, offering access to the 5GHz band for faster and more congestion-free connectivity. The Apple Watch SE is limited to 2.4GHz only, although it does still pack in the same Bluetooth 5.0 chipset, which is an improvement over the S3’s Bluetooth 4.2.
