Default Curious longlived battery

wrote in
:

ca 1995 I bought some 7yr diver watches from Woolworth. WHen they
doed I tried to replace the battery but the entire watch was sealed in
silicone and could not be salvaged. I had tied one of those watched to
the handlebar of my bicycle, face towards the sky. It still runs. Is
it because the battery remained flat? It is kinda miraculous!
