We were celebrating my older brother getting accepted into high school.
My father gave him this Seiko Mechanical railway pocket watch as a gift for getting in.
My father said "The shinkansen bullet trains are always on time thanks to this watch".
My brother didn't look all that happy. It was really weird for high schoolers to be walking around with a pocket watch even 40 years ago.
To this day, there is a spot to put this watch next to the driver's seat on the train.
I remember this whenever I see one.
