Montgomery dial
A minute-marked dial numbered for every minute, associated with American railroad use.
Explanation
The Montgomery dial numbers every minute around the edge, with the five-minute figures in red or emphasised, so a conductor could read elapsed minutes instantly. Named for railroad watch inspector Henry S. Montgomery, it was adopted or required by several American railroads in the early twentieth century (exact dates vary by line). Original Montgomery dials in good condition are sought after.
