Nothing clarifies the water resistance capabilities of the CMF Watch Pro 2 and Watch 3 Pro. While these devices carry an IP68 rating, the company maintains a clear distinction between water resistance and a waterproof designation. This rating ensures the watches remain dust-tight and can survive limited freshwater exposure in controlled environments.
Users should note that the IP68 rating is not a license to wear the devices in all wet conditions. Nothing explicitly advises against wearing the CMF watches during swimming, showering, or inside saunas. The internal testing reflects controlled conditions rather than the variables present in daily activities or prolonged submersion.
Water resistance is a feature that degrades through regular wear and tear. Even though some independent tests show these watches can survive up to 30 minutes underwater, the manufacturer guidance takes precedence. The CMF Watch 3 Pro remains a strong budget contender for those who need a device to handle rain, sweat, and common spills, but the official stance remains firm on avoiding deliberate immersion.
For those seeking a watch for swimming or intense open-water activities, Nothing suggests selecting a device specifically rated for those tasks. The IP68 certification covers ingress protection against solids and specific water exposure, but it does not account for the high pressure or temperature shifts found in pools or steam rooms. Relying on the official guidance helps ensure the longevity of the device hardware.
