A nice example of a classic 214 Accutron. Apparently the word "Waterproof" was used initially and then changed to "Water Resistant" in 1969. Later in 1969, all reference to water resistance is removed. It was added again after 1971 to increase flagging sales, but I must make the following cautionary statement:
Accutrons are NOT waterproof, and never were. Even excessive wrist sweat can fog them up, and entry is provided, especially in the 214, at many points, not the least of which are the setting mechanism and battery hatch. If you have a nice old Accutron, treat it kindly, and keep in mind also that the stainless steel on these will also corrode over time when exposed to moisture, most commonly around the crystal, in the seat, where it cannot be seen unless the crystal is being changed. Your Accutron has survived all these years, it would be a shame to lose it to corrosion or water damage.

This 422 is similar, but I believe its a different dial, case, and movement variation. I have one. While the 422 is not railroad approved, the watch with the chapter ring is railroad approved. It says so on the dial. It might not be North American Railroad approved, but it is Swiss Railroad approved, since its a swiss movement, case, dial and is not a North American release. (As Astronaut M2 points out below.)

Sorry, you are right. I just noticed that the "Railroad Approved" was missing. Most of these say Railroad approved, and look identical aside from the RR approved. Interesting. I didn't realize there were two different versions that look nearly identical where one is Railroad Approved and one is not.
