The Casio "G-Shock" (59 USD) that I have used for years to take celestial sights gains only a second every three months. Since the change has always been predictable, I have been able to correct for watch error if necessary and complete very satisfactory sight reductions. The accuracy of the sight whilst bouncing around in the chop has been the bigger concern. I find myself suffering from the precision "malady" in the piloting and navigation classes I teach. Obviously we want to strive for the utmost in accuracy in a classroom setting while learning and practicing the skills, but we tend to fall into a "nearest tenth" mode...only to become frustrated once out in the real world - where the decimal places often round themselves to whole numbers no matter how hard we try to be precise. Thus the constant caveat: "The prudent navigator never relies upon a single means of fixing his position". P/Lt/C Michael A.
