CMF Watch Pro 2 and CMF Watch 3 Pro models feature IP68 dust and water resistance ratings, according to specifications from Nothing. While the budget smartwatches can withstand dust-tight conditions and limited freshwater exposure under controlled testing, Nothing advises users not to wear the devices while swimming, showering, or using saunas.
Understanding IP68 Ratings on Budget Smartwatches
According to Nothing, the CMF Watch Pro 2 and newer CMF Watch 3 Pro carry IP68 ratings for dust and water resistance. An IP rating, or ingress protection rating, uses a two-digit scale where the first number indicates protection against solid particles and the second number represents liquid resistance. A rating of six for solids means both smartwatches are fully dust-tight. The eight rating for water certifies resistance to continuous immersion under manufacturer-defined conditions, according to technical standards.
However, an IP68 certification is a controlled laboratory rating rather than a blanket guarantee of waterproof performance. Water resistance degrades over normal wear and tear. Because of this degradation, Nothing specifies that the watches are built to handle rain, sweat, and everyday splashes, but they are not designed to function as dive watches or withstand prolonged submersion.
Real-World Water Testing Versus Official Guidance
Independent testing on platforms like YouTube shows that earlier models, such as the original CMF Watch Pro, can survive up to 30 minutes underwater during specific tests. These real-world results indicate the hardware can handle accidental liquid exposure during daily life. Even so, testing outcomes do not override the manufacturer’s operational limits.
Pro Tip: Wipe your CMF smartwatch dry immediately after exposure to sweat, rain, or accidental spills to help preserve the longevity of its seals and maintain its water-resistance limits over time.
Positioned as value-first alternatives to high-end wearables like the Apple Watch, the CMF lineup focuses on lightweight builds, built-in GPS, and extended battery life. Buyers seeking a budget Android smartwatch for routine daily wear will find the hardware capable of shrugging off minor moisture. Users requiring consistent wet exposure, pool training, or open-water workouts should look to dedicated dive or swim watches, according to Nothing’s official guidance.
Frequently Asked Questions
Are CMF smartwatches waterproof?
No. According to Nothing, the CMF Watch Pro 2 and CMF Watch 3 Pro are water-resistant with an IP68 rating, not waterproof.
Can you swim with a CMF watch?
No. Nothing explicitly advises against wearing CMF smartwatches while swimming, showering, or using a sauna.
What does IP68 mean for CMF watches?
The IP68 rating indicates that the watches are completely dust-tight (the number six) and protected against continuous immersion under specific manufacturer-tested conditions (the number eight).
Will water resistance last the lifetime of the watch?
No. Water resistance naturally degrades over time with normal wear and tear, which is why everyday exposure like rain and sweat is recommended over deep-water immersion.
