SYi kVOR rZ OF 7-.-l 14,O^P=LZ WE LIVE f/V Time without stop ... precise, unceasing time in a watch untended, free of human care. This is Continuous Time, the special province of the Hamilton Watch Company where service through accurate timekeeping is a particular concern. The world's first Electric* watch and the self-winding watch already are symbols of our age where, more and more, machines serve man continuously, dependably, without supervision or attention. Continuous Time will also be contained within the ultimate watch. It will probably be a Hamilton, too.
