Nice little item. Totally useless in today's world but it'd be nice to have if the price is right.
It could have been used by:
A sonar operator to time return pings, thus distance from target?
A Torpedo Officer to time a torpedo run from launch to impact?
A Deck Officer to time depth charges from surface impact to detonation?
I don't know for sure. It will require a lot of research.
Does $250 sound unreasonable? I know very little about pocket watches but would love to pick something up..
