Famous For Its Accuracy 



It's just as easy for you to have accurate time as it is for these 

 railroad men. It's easier in fact, for your watch doesn't get the 

 constant vibration their watches have to stand.

"The Watch of Railroad Accuracy*' 



Over 75% of the value of a fine watch movement is invisible. It is the time, 

 care and skill employed in putting it together, and in making the minute final 

 adjustments, that constitute the difference between a fine watch movement and 

 one which merely looks like it. 



Write for Hamilton Watch Book "The Timekeeper** which 

 will enable you to appreciate the good points of a high-grade watch. 



The lowest-priced Hamilton is a movement alone for $13.00 ($14.00 in Canada). 

 The highest-priced Hamilton is our Masterpiece at $150.00 in 18k extra-heavy 

 gold case. Other Hamiltons at $26.50, $30.00, $40.00, $55.00, $80.00, $110.00. etc. All 

 have Hamilton accuracy, beauty and durability.
