THE WATCH OF RAILROAD ACCURACY NOW MEETS THE TEST OF THE SKIES! FROM JULY HEAT OF EARTH TO 57° BELOW ZERO AT TWELVE MILES UP HAMILTON ACCURACY IS UNFAILING The Hamilton was the official watch of the latest flight to the Stratosphere-the National Geographic Society-U . S. Army Expedition. Ten IIamiltons rose with the great balloon. One was a part of the swinging spectrograph which was carried outside the gondola, and which came to earth uninjured. In a letter from the famous Bausch & Lomb Optical Co., Rochester, N. Y., appears the following statement: "This spectrograph, made to record the energy dis tribution of sunlight in upper regions, was provided with one of the Hamilton watches to record time on the film which carried the records. This watch worked perfectly all during the flight with tempera tures to 57 degrees centigrade below zero. When the instrument landed, the watch was in perfect run ning condition and no time lag could be noticed." Trustworthy Hamiltons were also integral parts of the cosmic ray detector and aerial cameras, whose film records provided additional vital research data. Wherever accurate time-keeping is required, the Hamilton Watch may usually be found. Ask your jeweler to show you the Hamilton. Many models of beauty and distinction from $35 to $500 for men and women-pocket, strap and wrist. Illustrated folder picturing latest models gladly sent upon request.
