    Re: The ultimate celestial navigation time piece

    Tony,
    For the eccentric minority who like to use mechanical, non electronic time 
    pieces, I have details on 2 affordable (under $100), automatic, modern build 
    watches with regular, chronometer type  going rates.
    Please use private email and I can send more details.
    Best wishes
    Francis

    As Frank has correctly guessed about me being a technophobe (to some extent) - 
    I'm trying to avoid everything electric/electronic/modern. More so - in the 
    field of Emergency Navigation.
    I'm modelling a replacement handle - a grip rather - for my sextant. This grip 
    is thought to be a thick roundish plastic board (approx the size of ping-pong 
    bat) with holes for all five fingers separated around the central area, where 
    a split-system stop-watch (mechanical, of course!) will sit - face to the 
    palm. An index finger will be aligned at the split/resume button.
    I intend to do it like this:
      -- with some reference watch I am to start the stop-watch at a full minute of UTC;
      -- to write down that time in a log-book;
      -- to shoot a sight and press the split/resume button freesing one of the 
    stop-watch arms - to be able to write down the stop-watch readings without 
    any hurry - along with the sextant's reading;
      -- having the angle and time interval readings properly recorded - to press 
    the split/resume button again (preparing the stop-watch for the next sight) 
    and proceed with the sighting as described in the previous step;
      -- when finished with all the sights - to use the reference watch to stop 
    the stop-watch on some full minute of UTC;
      -- to write down that reference watch readings;
      -- to use the recorded stop-watch intervals to place the sextant readings on 
    the UTC time-scale accordingly.
    
    I guess this is how it is/was done by serious navigators.
    The only question remains - where a techophobe gets a reliable mechanical 
    "reference watch" (for little money, I mean)?
    :)
    Regards,
    Tony
