Hamilton Watch Company Montgomery Railroad Dial No. 258
The No. 258 Montgomery Dial frequently appeared in advertisements by the Hamilton Watch Company aimed at the railroad industry.
The dial features heavy Arabic hour numerals and the familiar continuous marginal minute indicators around the perimeter, a style originated by Time Inspector H.S. Montgomery.
The earliest variant of the No. 258 dial is characterized by more stylistic hour numerals, with flourishes and terminals extending from several figures at an angle. Around 1915, the company updated this style to exhibit heavier numerals with terminals extending vertically, using a more structured form.
The No. 258 dial is commonly found on the 18-Size Grade 940 and the 16-Size Grade 992, two of the most popular railroad watches during this era.
