1926 Hamilton 992L Railroad Approved Pocket Watch

Hello Fellow Collectors. I thought I might put up a few of my Vintage Railroad approved pocket watches today. There were several American watch companies that produced watch under the standards set up to keep trains from having accidents. A typical railroad's requirements for a 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 o'clock
minimum of 17 functional jewels in the movement
16 or 18-size 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
