Don’t Swim with a Smartwatch, Whatever the Manufacturer Says

Smartwatches are becoming increasingly popular due to their high IP ratings, which indicate their waterproof capabilities. However, a recent incident serves as a cautionary tale about wearing these devices while swimming. A Reddit user, mangoed, decided to take a swim in the sea wearing a Samsung Galaxy Watch 5 Pro, which boasts a 5ATM+IP68 rating. This rating suggests that the watch is sealed from dust and can withstand immersion in water for an extended period. With a 5ATM rating, it can handle pressure equivalent to a depth of 50 meters, making it seem safe for a dip in the sea.

Unfortunately, after the swim, mangoed discovered that his watch had stopped working. Upon inspection, he found a significant amount of salt buildup inside the watch, leading to corrosion on the haptic motor and rusting of metal parts. Despite being able to clean and repair the watch, this serves as a valuable lesson for all smartwatch users.

It’s important to note that IP certification tests for devices are conducted in clean, fresh, still water. Therefore, exposure to salty, chlorinated, or moving water can still damage a smartwatch. Samsung confirms the water resistance ratings of its smartwatches but advises against prolonged submersion, swimming in fast-moving water, and exposure to disinfectants or salt in pool or seawater.

Even a visit to the swimming pool can pose risks to smartwatches, as chlorinated water can damage sensitive components or cause short circuits. Contaminants in natural bodies of water can also have adverse effects on devices. While some smartwatches, like the Honor Watch 5 Pro, claim to be suitable for swimming in pools and the sea, most devices are not completely waterproof.

Repairing a water-damaged smartwatch is possible by cleaning the affected parts with isopropyl alcohol, drying the watch, and recharging it. If the device is still under warranty and the manufacturer promises waterproof capabilities, returning it for repair or refund is an option. However, attempting to seal areas like the microphone and pressure sensor before swimming is not recommended.

In conclusion, while smartwatches may have high IP ratings, it’s essential to exercise caution when using them in water. Price and brand do not guarantee water resistance, and cheaper models may offer lower protection. Before swimming with a smartwatch, it’s crucial to understand the limitations of its water resistance and take necessary precautions to prevent damage.
