^^mltniuion tcli "The Watch of Railroad Accuracy" Used for Navigation-" Far more accurate than the average chronometer," says Captain in U. S.N. Thefollowing letter, recently receivedfrom an officer of the Navy, speaks bor itself. The signer's name is omitted for reasons of naval etiquette. HAMILTON WATCH COMPANY Lancaster, Pa. Gentlemen:-The watch purchased from you in December, 1913. is a marvel of accuracy. On January 1, 1914, it was set 22 seconds fast, on standard mean time, and throughout the year frequent comparisons were made which showed a steady and regular gain. On January 1, 1915, it was again compared and was found to be 1 minute 35 seconds fast, or a gain of 1 minute 13 seconds in 365 days, which is equivalent to a gaining rate of 0.2 second a day, or 6 sec onds a month. Had the rate of gain been variable, it would have been very different, but running as steadily and uniformly as it did, I would have no hesitancy whatever in using it for navigational purposes, as it is far more accurate than the average chro nometer used for this purpose, and much more convenient. (Signed) IMAGINE yourself carrying this very watch-it was not an expensive watch. Wouldn't you derive an immense satisfaction from the comfort, convenience and companion ship of so accurate a watch?
