Condorlover (I forget your name I'm embarrassed to say) your watch likely had tritium on the hands and numerals, hence the yellowing. Of course nowadays tritium is a big no no but many other, safer applications have taken its place such as super luminova.
I shall look into the West End Watch Co in the morning, just out of curiosity. Of course many 'labels' used Swiss movements and stuck their names on the dial. You might even have an early Omega inside that case!
BTW, thanks so much for the kind words. An explanation for my disappearance will be posted soon.
Regards,
Jay.
