The “Santa Fe Railway System Standard Dial” with Montgomery minute numbering was unique to the Santa Fe line. Henry S. Montgomery was Santa Fe Railway’s general watch and clock inspector from 1896 to 1923, and by 1906 perfected a dial with upright minutes, from 1 to 60, printed on the outermost part of pocket watch and clock dials.
Unlike the smaller and more widely used Santa Fe standard station clock – with identical dimensions except for a shorter pendulum and six-inch shorter pendulum box – the “World” model regulators have a printed circle on the dial, containing a second hand. The circle is located above the center shaft holding the minute and hour hands.
This dial was commonly used on Seth Thomas regulators including the “short-drop”, “World”, and Regulators No. 2, No. 3, and No. 19.
