The OUAW AKIN collection, with free flowing sand behind sapphire glass is water resistant but NOT waterproof. It is resistant to everyday use and to light rain. We recommend avoiding wearing the jewelry while swimming, bathing, and diving in fresh or sea water.

All other OUAW jewelry is waterproof.

The general recommendation for almost every piece of jewelry, OUAWs or other, is to remove your jewelry when swimming, taking showers. We recommend the same. And never ever wear jewelry in natural hot springs as found in volcanic areas.
