An astounding watch. Feel free to do your research of course, but this is the Borazon Lady from Technos. The firm at this time was Swiss, before the marque was sold to a Brazilian organisation later on. The case is made out of Borazon Carbide. It's extremely hard wearing and as such is in exceptional condition. The crystal is something else also.. It's made out of Cut Glass. Ive attempted to show that in the little movie here. It's a 10mm lug if you wanted to fit a leather strap. Contact me if you'd like to discuss postage. Do not choose postage please, I will cancel the sale if I do not feel it is secure to post - this is now a rare and sought after watch and needs to be treated as such. I do not post to the USA or Italy.
