The Apple Watch does have Bluetooth capabilities, but unfortunately, it does not work underwater. Bluetooth signals are radio waves that can be easily disrupted by water. When you submerge the Apple Watch in water, the Bluetooth connection is likely to be lost or significantly weakened.
This limitation is due to the nature of Bluetooth technology itself. Bluetooth operates on the 2.4 GHz frequency band, which is also used by many other wireless devices, such as Wi-Fi routers, cordless phones, and microwaves. The water molecules in the environment can absorb and scatter these radio waves, leading to a loss of signal strength and range.
Additionally, the Apple Watch is not designed to be used underwater. While it may have some level of water resistance, it is not suitable for prolonged submersion. Apple states that the Apple Watch Series 3 and later models have a water resistance rating of up to 50 meters, but this is mainly for protection against splashes, rain, and accidental submersion while swimming or doing water-based activities. It is not intended for scuba diving or other deep-water activities.
If you want to listen to music or use Bluetooth headphones while swimming or engaging in water activities, there are specialized waterproof headphones available on the market. These headphones are designed specifically for underwater use and have a higher level of water resistance than standard Bluetooth headphones. They often use different wireless technologies, such as bone conduction or radio frequency, to transmit audio signals underwater.
While the Apple Watch has Bluetooth capabilities, it does not work effectively underwater due to the limitations of Bluetooth technology and the design of the device itself. If you want to enjoy music or audio while swimming or engaging in water activities, it is advisable to look for specialized waterproof headphones that are specifically designed for underwater use.
