    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.

    | the watch to Zulu and then adjusted the 24 hour hand to the zone times
    | being kept on board since I could make these adjustments without losing
    | Zulu time on the other hands. Here is a picture of the watch:

    Thank you for that information, Gary. 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?
