being 'the man from '64' i often come across Dennison cased watches so this information will always be handy to me. one of the things i particularly like about them is the fact that they are english and our assay system is the best in the world (i suppose it would be as we started it). the assay marks clearly state what year the case was assayed which makes a year specific collection a lot easier.
thanks again for all the hard work
