Lindell V. RiddleWelcome to IHC185 Mario,
Just to add a little, your approximately 1958 production 992B was based on an entirely new design introduced in October of 1940 produced until 1970 and appealed mainly to Railroad employees. One of the most basic Railroad Watch Requirements was Lever-Setting for the reasons described by others in this topic.
Consider this scenario, if you pull a stem-set watch out of your pocket you might without realizing pull up on the crown thereby changing the time indicated on the watch. With the lives of many people and a great investment in equipment at stake the trains had to be precisely timed in order to, for example change tracks or pass each other without a risk of accident. For that reason Railroad Watches were regularly inspected to guarantee the timekeeping ability of plus or minus 30 seconds over 7 days. Other requirements including Lever-Setting became mandatory for all Railroad Pocket Watches during the first decade of the Twentieth Century, most of the Railroad Standards are still in effect today.
In your 992B you have the most modern, most reliable and easiest to service of all Railroad Grade Pocket Watches, it's timekeeping ability is on a par with the finest Swiss-Made Chronometers.
Many of us enjoy collecting 992B Hamiltons and they are increasing in value.
