The watchband does not have markings because it was made by my great uncle for my Grandfather. It is real turquoise. As far as the age, I'm not sure exactly of how old it is but my grandpa wore it for quite a while and he passed away in 1996. I took some more pictures for you to see a little closer the details. Hope this helps... BTW the purple watch is a "Quartz Gossip".
