A Hamilton's Record on Pike's Peak "From a difference of hot sum mer at the bottom to the arctic regions at the top, my Hamilton gained just three seconds a month, from February to August, or a total of twenty-one seconds only on the whole job of construction," writes A. G. Allan, Chief Engineer of the Pike's Peak Highway, whose picture is shown here. It is literally after a Hamilton Watch is made, that work vital to its accuracy under varying conditions begins. The delicate mechanism must be adjusted to heat and cold, or such a record as the one above would be out of the question. And "heat and cold" is only one of a series of adjustments necessary to Hamilton standards of accuracy. "The Watch of Railroad Accuracy" Records of accuracy like this one (phenomenal, except when considered as the work of a Hamilton) explain why the Hamilton is preferred by scientific men and by railroad conductors and engineers. It meets their most exacting requirements. Ask your jeweler to show you the various Hamilton models. There are thirty in all, for both men and women. They range in price from $12.25 for movement alone ($13.00 in Canada) to $150.00 for the superb Hamilton Masterpiece in 18k extra heavy gold case. Thin models at $28.00, $40.00, $55.00 and up. Ladies' Bracelet Watches at $30.00 and $45.00. All have Hamilton Accuracy, Beauty and Durability. Write for Hamilton Watch Book "The Timekeeper" It pictures and describes all Hamiltons and tells interesting facts about watch making. A reading of this book gives you a new perspective on watches and watch buying, and may save you from buying the kind of watch not suited to your requirements.
