"WATCH OF AIRLINE ACCURACY" TWA makes "railroad watch" standard for time aloft THE GIANT new TWA"Sky Chief" faces down the ramp. As the cabin door is closed, the stewardess glances at her Hamil ton, for her "log" must give departuretime on the nose. At every stop from coast to coast, a score of times aloft, Hamilton aeC curacy serves "the Lindbergh Line." Thus "the watch of railroad accuracy" now also becomes "the watch of airline accuracy." No matter how exquisitely dainty the debutante's watch, or how slenderly curved-to-the-wrist the man's strap model, accuracy is a strictly observed Hamilton law. Hamilton makes no watches with less than 17 jewels, no watches cased in less than the finest quality platinum,, solid gold or gold filled. Ask the leading jeweler in your city what watch he recommends. He'll probably suggest a Hamilton; and with prices as low as $37.50, there's no need to own less than the finest.
