Cool story. A little scrubbing and bleach and it'll be good as new! Recycle, recycle, recycle!
When I was a kid, my father, brother and I were using a backhoe to build a gravel and dirt dam in our stream. There was a big barn beam across the narrowest part, where we were dumping the fill to create the dam. My brother took off his Timex watch and laid it on the beam. In no time, dirt and gravel had been dumped on top and then scraped off the beam, taking the watch with it. We didn't realized until the work was all done. My brother's watch was deep inside the dam, under rushing water, by that point.
About 10 years later, I was crossing the stream, on the beam and I saw a reflection. The dam had settled a lot and much of the soil had washed away, leaving a pile of gravel across the bottom of the stream. The flash was the face of my brother's watch! I fished it out, cleaned it up, wound it (not a digital watch) and it began ticking away. I wore it for many years after that. It kept perfect time, even though it had spent about 10 years under water, in a pile of gravel and dirt and through hot summers and bitterly cold winters.
I wouldn't be surprised if millions of years after humanity has disappeared, our "stuff" will still be visible, all over the planet!
