"...turned in their case to place the crown at the vintage 1:30 position, a location favored by many early 20th century railroad watches."
What the fuck? Do show me an early 20th century railroad wristwatch. None? Good, because there weren't any. Railroad wristwatches were a thing of the 1950s. 19th and 20th century railroad PWs were pro maiori parte in a lepine (open-face) configuration with crown at 12, maybe also some "sidewinders" with crown at 3, but no front cover (as a savonnette aka hunter configuration would have). Crown at 1:30 makes no sense in a pocket watch, and PWs were pretty much the only railroad watches of the early 20th century.
The small movements of wristwatches and ladies' pendant watches could well have been made to a similar standard as railroad chronometers, but that doesn't make the watch a railroad one.
The crown at 1:30 could have had two reasons for it to be there:
a) the manufacturer used a movement previously intended for a ladies' open-face pendant watch
b) the watch was intended for the military, pilots or drivers - that configuration is practical when you hold a steering wheel, a yoke or a rifle, and wear the watch on the inner side of the wrist to keep an eye on it at all times.
Reason b) does not exclude reason a).
You cannot explain away a wantonly immoral act, because you think that it is connected to some higher purpose.
