By 1917, the Hamilton Watch Company had been in business for 25 years. Their timepieces were famous for their accuracy; much of America’s enormous railway network depended on them for both safety and efficiency.

This 1917 Grade 992 sports a flawless example of the highly coveted “Montgomery dial,” created by Santa Fe Railway Watch and Clock Inspector Henry S. Montgomery. The outer track displays individual minutes numbered from 1 to 60.

It’s hard to overstate the skill required to create a movement precise enough to take full advantage of a 60-minute Montgomery dial. More than 100 years later, this Hamilton’s movement continues to uphold Lancaster’s lofty standards.

The movement sits in a silky smooth nickel case, free from signs of wear and tear. Taken as a whole, this Hamilton Grade 992, Model 2 represents the height of early 20th century horology. It’s ideal for daily carry or on display – a not-so-silent testimony to American ingenuity.
