American Railroad Pocket watches were amongst the highest grade watches made, having been made for the railways makes them a great choice to use every day, mainly for their durability over time. Their lower production quantities and of course their high grade movements make them also a great gift or investment.

A typical railroad's requirements for a pocket watch in the early 20th century might include:

  • Only American-made watches may be used (depending on availability of spare parts).
  • Only open-faced dials, with the stem at 12 oclock.
  • Minimum of 17 functional jewels in the movement.
  • Size 16 or 18 only.
  • Maximum variation of 30 seconds (approximately 4 seconds daily) per weekly check.
  • Watch adjusted to at least five positions: Face up and face down (the positions a watch might commonly take when laid on a flat surface); then crown up, crown pointing left, and crown pointing right (the positions a watch might commonly take in a pocket). Occasionally a sixth position, crown pointing down, would be included.
  • Adjusted for severe temperature variance and isochronism (variance in spring tension)
  • Indication of time with bold legible Arabic numerals, outer minute division, second dial, heavy hands.
  • Lever used to set the time (no risk of inadvertently setting the watch to an erroneous time, when winding the watch with the stem)
  • Breguet balance spring
  • Micrometer adjustment regulator
  • Double roller escapement
  • Steel escape wheel
  • Anti-magnetic protection (after the advent of diesel-electric locomotives)
The minimum requirements were raised several times as watch-making technology progressed, and the watch companies produced newer, even more reliable models. By WW2, many railroads required watches that were of a much higher grade (as many as 23 jewels, for example) than those made to comply with the original 1891 standard.
