I also just noticed that the $17.00 Armitron digital watches that I
have been using for my chronometer experiment also have two time zones,
two lap times and illuminate at night.

George, many digital watches (for example the Timex Indiglo Ironman) keep two time zones and are not expensive. The Indiglos also light up and store lap times which can be used to store the times of the sextant shots. http://shopping.yahoo.com/s:Watches:4168-Brand=Timex:4518-Watch%20Features=Indiglo gl On Nov 13, 4:41 am, "George Huxtable" <geo...@hux.me.uk> wrote:Gary wrote- | | I use my Torgoen T5 watch.

That seems a really sensible arrangement of hands, for the likes of us. Do you happen to know that same design exists in cheaper watches, for thise of us for whom the very-best is more than good enough?
