Split stopwatches will cost you
Most probably yes, but I already has got one for cheap. :)
I was surprised to discover that it can go for ~17 hours from full winding-up.
As I've described - the main idea of my custom grip is to have the stop-watch in the palm while holding the sextant. Sort of a "sub-second" accuracy of a sight timing. Hope it will be important for lunars.
