I have had a couple of cheap gold-tone watches that I tried to chip away the (assumed) outer layer to see what the metal was like underneath. It has been a while since I did this, but it seems like they were purely the same metal throughout. So, it seemed like there was no outer layer.
Was it brass?
What type of goldtone metal does Timex use? I think one of the watches I tried was a Timex.
Thanks for any information. (I'm also interested in silver/steel-toned watches.)
