No. None of our scales are waterproof.
The top of the Acaia Pearl is completely smooth with no buttons that stand out. The material is acrylic. If water is accidentally spilled on top, it will run down the sides and the scale will not be damaged. If you submerge it in water, then you are risking the scale and its electronic parts. We do not recommend submerging it in water.
Waterproof vs Water Resistant
To claim a product is waterproof, you are required to test and certify them. This includes operating them underwater. Since the Acaia Lunar cannot be operated underwater, we do not claim that it is waterproof.
