National Geographic : 1942 Apr
AMERICA MARCHES FORWARD ON TIME! GUNS SHOOT BETWEEN the whirl ing propeller blades on America's fighter planes, mighty shadows of destruction. Realize that those blades roar around as fast as 3500 times a minute-and try to imagine the unbelievable preci sion required to fire between the blades. Hamilton is proud of the part its instruments play in this precision operation. "UNIDENTIFIED PLANE at 7:27," notes Bill Todd, air-raid spotter, in his logbook. Hour after hour today, all over America, on quiet hillsides, deserted roof tops, gal lant men and women are scan ning the skies for your safety. As Bill Todd phones the near est interceptor command, the Hamilton on his wrist becomes a vital cog in the wheel of American defense. HAMILTON'S major effort is going Z into the war program. But some Hamiltons are still available. And Hamilton's experience in build ing watches for railroad men in sures the greatest possible accu racy in every size and grade. All Hamilton Watches, except those for military use, have precious metal cases, 17 jewels or more. Styles for men and women from $41.25 up (Federal tax included). Made in U. S.A. Hamilton Watch Company, 244 Columbia Ave., Lancaster, Penna. "Mention the Geographic-It identifies you."
