then pull it to change the alarm
Turn 30 degree up..then you jump every time between hours and minutes and alarm set or not, turn down and you change to a later hour.
Pull in time mode and you can set time/date
So a bit difficult to set then
I have a seiko 0139 that has a crown and it's the same idea as your timex, and is also difficult to set, but not as complex.
