"Sea Glass Colors" inspired by sea glass. "Sea glass," also called "jewels on the beach," is made of broken bottles and other pieces of glass that have been rubbed round by waves over long periods to form beautiful frosted glass. A matte blue skeleton material has been used for the case and band to go with this sea glass motif. The brilliance of the gold metal parts on the face is evocative of the light reflected off sea glass, creating a design that can be worn like beach jewelry.
