The Garmin Fenix 8 and Apple Watch Ultra have different water resistance ratings:
Garmin Fenix 8
- The Fenix 8 has a water resistance rating of 10 ATM, which means it can withstand water pressure equivalent to a depth of 100 meters (328 feet) [1][3].- This allows the Fenix 8 to be used for swimming and even recreational scuba diving down to 40 meters (131 feet) [1].
Apple Watch Ultra
- The Apple Watch Ultra has a water resistance rating of 100 meters under ISO standard 22810 [1][3].- This is the highest water resistance rating ever on an Apple Watch, making it suitable for recreational scuba diving to 40 meters (131 feet) as well [1][3].
- The Watch Ultra is also certified to the EN13319 standard, which is an internationally recognized standard for diving accessories [1].
In summary, both the Garmin Fenix 8 and Apple Watch Ultra have impressive water resistance ratings that allow them to be used for swimming and recreational diving down to 40 meters. However, the Watch Ultra has a slight edge with its 100-meter rating under the ISO 22810 standard, as well as the EN13319 certification for diving accessories.
