I think we have been through this discussion before (see archives) ..
the most readily obtainable solution is a stop watch designed for car
rallies that "freezes" clock time. I did actually make an Arduino
sketch that freezes and replays a  real time clock  with this
intention. What I didnt do is make a nice case for it, so it would fit
on my sextant with a nice button.
