I'm going to measure the depth of the pocks, then the crystal thickness. Personally I

think the marks were made by sandy rocks contiuously beating against the crystal. If I'm not mistaken, which I easily could be, the glass is made from sand. That being the case, it makes sense as to its erosion properties. The watch was found in a freshwater dive. I'm heading to the east coast in less than 2 weeks for a saltwater dive, hopefully I can find something interesting there. I'll post bracelet pictures later today. There is surface rust beginning on the inside of the bracelet. At least it appears to be rust.
