    Re: mechanical chronometers

    I can't help but offer a cheap and simple solution to your quest, even
    though it is obvious.  Why not use a cheap quartz clock for your
    reference time.  Roll your own mathematical function that modifies
    the reference time in a manner that simulates a mechanical
    chronometer.  I am certain you can find plenty of information
    regarding the accuracy of mechanical chronometers.  You could
    even simulate simply a typical three chronometer arrangement
    based on one quartz reference.  This involves minimal initial buy in
    cost and certainly does not require any service fees later.  Just think
    of the fun you could have tinkering with the function.

    I think I have just saved you a bundle of money, what will you spend
    it on?

    As part of my plan to immerse myself in the time of kepler, newton
    with respect to navigation and other things. I have been researching
    mechanical watches and chronometers. The only manufacturer of
    mechanical timepieces suitable for navigation is Russian the poljot

    At 1500.00 us dollars the price does not seem out of line. What I
    concerned about though is either learning to maintain the device or
    someone who can.

    I know quartz, electronic watches are dirt cheap and more accurate
    but it is outside the parameters of the game. After all I can just
    turn on the gps and make all these subtleties go away.

    Anyone have direct experience with the 6mx and what effort or
    costs would be involved in keeping such a beautiful mechanical
    in good running condition?
